Title: My LS bike build
Post by: isiahstites on April 20, 2007, 10:40:52 PM
Hello all my name is Scott and I thought I would document my build here as I have been foloowing the site for awhile now. Seems to be good people here, thanks for all of the knowledge here it has been very helpful.
I picked up the donor bike a few weeks ago for a $1000, it is a 98' Buell S3. It has a blown motor, thus the reason it was so cheap and it has some real bad bubbling on the tank. The motor is going to get rebuilt from top to bottom so I did't mind the it being blown. The gas tank and most of the parts will be sold off so this was not a concern of mine either, however the front end, and wheels will be used in the build.

This worked out perfect in my mind as I got a complete bike for 1k instead of paying 4k for a running one when I was going to gut the motor anyways.

More pics and info to follow as I get into the motor and see how bad it really is.........

Scott

I pretty much finished up with the disassembly of the Buell this evening with the exception of the swingarm. I will remove the swingarm this weekend as well as the cams from the motor I scored last weekend. The cams and the heads are off to NRHS first thing Monday for the headwork and I believe the cams are going to Redshift as a core in exchange for the new cams.

Met with Randy at MDR this afternoon and discussed my chassis design. We should start building the chassis very soon. The bike will be equipped with plastics from Airtech. All motor components are coming from NHRS performance. The motor will be 82 c.i. (1350) and will get new cylinders, pistons, cams, and a complete work over of the heads.

Welcome to the website.

Aaron at NHRS sure has done his homework and real world testing of his components, at Bonneville, that he sells. Im sure you will be very happy. He is also a sponsor of the site.

Kent at AirTech has been a blessing to work with also. I have gotten nothing but great service from them.

I'm curious will you convert that from belt drive to chain drive??

Jon

Thanks for the welcome Jon, you run one hell of site! Thank you.

I will convert to chain drive, it will make for simple gearing changes.

Can you help me figure out why I am not getting instant notifications.

thanks,

Post by: isiahstites on April 21, 2007, 06:37:27 PM
Today I pulled the cams out of both motors, I wanted to see the difference in the lobes from the stock Sportster vs the Buell and the stock sportster cams are off to NRHS to be sent to Redshift for there make over into the 643's. My heads are going to NRHS for a make over as well.

I also finished completely with the disassembly of the donor bike. If I have time tomorrow I will try and tear down the motor completely and split the cases so I can access what other damage may of happen and also to have a motor to use during the fabrication of the frame.

If anyone is in need of parts let me know as I will sell them on the forums I visit first and then move on to ebay and craigslist. Just about everything will be for sell with the exception of the the wheels, frontend, and motor. I may sell the frame later after I am done building. If you need a part just ask I may have it........

I spent some time after work last night on the motor. I was able to get the cases split and see if there was any damage to the cases. At this point I believe the cases are fine and that the rods are definatley screwed and I am not sure about the crank. I will press the crank out of the case this weekend to check and see what kind of shape it is in.

No worries on the crank or the rods as I am buying a set of Carrillo rods and I have another crank in another motor I can use.

Heads are currently at NRHS and should be back in about three weeks, pistons and cylinders are on order and the cams are being sent to Redshift via NHRS.

Scott,
Great job on posting the build photos and info. It's interesting to see what the bike guys go through.  Having worked on a gas altered and lakester for Bonneville, it is nice to see what it takes to put a bike together for Bonneville.  Pretty amazing those cases are still together from the looks of the piston.

Pat,

        Thanks for the praise it is appreciated! I was thinking the same thing about the cases........I was quite shocked that it does not appear that there is even a mark in the cases. I will know for sure this weekend when I press the crank out and can get a better look at the other case.

My Dyna (2ki) ignition came in yesterday and I am still waiting on a bunch of parts for the motor to arrive. Most parts are being custom made so I am still weeks out on alot of the parts. Ordered my rods today from Carrillo to the tune of $712 shipped to my door. They will be here tomorrow at which point I can order my crank pin and bearings.

I also decided that this year I am going to hold off on building a ground up chassis. Instead I have ordered a frame from Paughco after some good advice from a well known local land speed racer. The frame will be modded as necessary. Going this route will allow me to race this year in July at El Mirage prior to going to the Bub meet in September.

Also have been selling lots of parts off of the donor parts. if you need a part please ask I may want to sell.

Heh,

was this a rpm on the limiter with a shift back from the third into the first gear...or only a attempt to find the fastest way to recycle a piston.......

Didn't saw a so great blow up for a long time.

Have a great time to build your speed dream.

My frame came in last week and I had to go out of town for the week. I took the day off today and Friday for a four day weekend and in hope that I could get some work done on the bike.

I started to pound in the neck cups with a 4x4 and a hammer and realized that it was much more work than I felt like doing so I pressed them in with my 20 ton press I bought a few months ago...........man am I glad I bought that press.
(http://i142.photobucket.com/albums/r98/isiahstites/100_0996.jpg)

Put the rear wheel on after some clearancing to the axle blocks to fit my stock Buell axle. The brake rotor is going to have to ride real close to the frame if I can make this wheel work.
(http://i142.photobucket.com/albums/r98/isiahstites/100_0997.jpg)

Axle is going to need to be cut rewelded and pinned.........also I need to buy a sprocket and see if the chain will clear the frame........it is going to be real close.

Looking real good, keep the pictures coming.

You should have upgraded to the next model bike stand... It has a better wheel clamp in front, plus the air lift also.... Havent used the air lift part yet, but I have not had to tie the bike down on the sides at all with the better wheel clamp.

I agree that wheel clamp sucks! I bought that lift for one Ben Franklin so the price was right.

you probably have already figured for this but i have in the past twisted and broken similar frames from paugco with stroker street motors making less then 80-90 HP. just thought I'd throw that out there. neat project. Hope to run into you at BUBs.

I am afraid those incidents where before digital cameras or at least before i was aware of them. I had a 93 inch panhead that broke the top frame rail in two right under the gas tank after about a year. I found it when all of a sudden the bike wouldn't go straight as i was pushing it in the shop. I never figured exactly why. PAUGCO just gave me a new frame. I always had to reinforce the rear section because it would twist under acceleration with any thing that made serious ( OK shovelhead / panhead serious )  torque. Also I found the rear axle needed a way to lock it in position or it would pull the sprocket side forward cocking the wheel. I would add softtail type axle adjusters. These are just things i had happen but it was with big street motors on pavement caused by vibration and hard acceleration. Not saying the same conditions apply on a salt project. like i said just throwing it out there.
have fun

Update:
 
I bought a set of clip-ons from Kent Riches that I think will work out pretty well. All of the parts for the motor arrived last week and almost all of the machine work on the case is done with the exception of the upgrade to the anti-rotation pins for the lifters that I will do next week some time.
 
The motor is going to Bob Moreland in a few weeks to have the line-boring and balancing done.

The valve sizes on my is a 1.940" intake and 1.615" exhaust valves. A 30 degree squish badn was cut along with dual plugging of the heads and .700 lift springs.

I had a few things happen in my favor this week and it looks like I will be attending the World of Speed event in Bonneville in August so it looks like I need to kick this build into high gear.

I spent most of today at MDR turning down my rear wheel hub so I would have enough clearance inbetween the frame and the sprocket/chain. Intiallt the chain hit the frame, with Randy of MDR mentoring I turned the sprocket side down .300 and the disc side .200 and as you see in the pictures it looks like everything is going to be perfect.


We used a dial indicator to make sure the wheel was centered on the radius cutter attachment of the mill.
 (http://i142.photobucket.com/albums/r98/isiahstites/100_1102.jpg)

Once centered the cutting can begin........this is the sprocket side after .300 later.
(http://i142.photobucket.com/albums/r98/isiahstites/100_1098.jpg)

A picture of the wheel mounted on the radius cutter on the mill.
(http://i142.photobucket.com/albums/r98/isiahstites/100_1099.jpg)

Here is the axle cut to length. The top axle is a stock Buell axle and the second one is the shortened one and the amount that was cut off below the second axle. Randy N. bored out the center of the nut and turned down part of the axle and slid the two together and tig welded the two together.
(http://i142.photobucket.com/albums/r98/isiahstites/100_1106.jpg)


Here is my new clearance on the sprocket side.
(http://i142.photobucket.com/albums/r98/isiahstites/100_1107.jpg)

Here is my clearance on the disc side.
(http://i142.photobucket.com/albums/r98/isiahstites/100_1111.jpg)


I sent my cases to NRHS and they are balancing everything as well as assembling the bottom end.

I have been working on the rear brake bracket................here is a picture of the stock one which is way to wide to use in my chassis.

(http://i142.photobucket.com/albums/r98/isiahstites/100_1112.jpg)

And the begining of the new one
(http://i142.photobucket.com/albums/r98/isiahstites/100_1113.jpg)

Chucked up and ready for drilling
(http://i142.photobucket.com/albums/r98/isiahstites/100_1114.jpg)

Holes drilled and one screw hole tapped
(http://i142.photobucket.com/albums/r98/isiahstites/100_1116.jpg)

Welded this threaded coupler to the bracket after I tightened it down and the screw passed throught the bracket and the coupler to insure the threads were in time with each other. ( I think that's what you call it)
(http://i142.photobucket.com/albums/r98/isiahstites/100_1117.jpg)


Here is the completed bracket
(http://i142.photobucket.com/albums/r98/isiahstites/100_1118.jpg)

The other side
(http://i142.photobucket.com/albums/r98/isiahstites/100_1120.jpg)

With the caliper mounted.......I may not use this bracket as I ran into a problem with the clearances for the rotor because this is a floating caliper. I need to spend a little more time on it to correct the problem, however  icould easily make another bracket in a short amount of time and use a two piston caliper and that would solve my problem. I am going to look at other options later for the rear brake. I really need a break from working on the brake!

Oil tank is installed along with the battery box.

I suppose, while I'm at it, I should remind you that there need be no apostrophe in "Harley's".  But I expect you knew that and were just trying to get my goat.

Thanks Slim, I look forward to meeting you one day. While you are on your proof reading tear Speed Week is two words and not one.

That position has been filled and no rookies need apply.
You may wish to leave your resume with the HMFWIC, but recognize it is a lifetime appointment. :wink:

That is 2, and only 998 more to go before I can go back in the garage per Sami.

And in this year's "Official" program, SpeedWeek is spelled SpeedWeek. Sorta like some proprietary thing.

Been a busy weekend! I got my spare motor put in so I could line up the rear sprocket and figure out the offset needed for my trans sprocket. All of my sprockets are on order and being made at PBI. Had my heads flowed and was pleasantly surprised to find out that the motor has the potential to make about 133 hp if I can tune it and build a good exhaust system. Got lots of parts ordered and on the way. I have about 30 days left and it is going to be close. I hope I can make it............


Got the footpegs and shifter completed.
(http://i142.photobucket.com/albums/r98/isiahstites/100_1124.jpg)

Grinded, shaped, drilled and sandblasted peg mounts.
(http://i142.photobucket.com/albums/r98/isiahstites/100_1126.jpg)

Mounts welded on.
(http://i142.photobucket.com/albums/r98/isiahstites/100_1129.jpg)

Shifter rod was made of aluminum stock. I drilled and tapped the ends for the heim joints.
(http://i142.photobucket.com/albums/r98/isiahstites/100_1165.jpg)

Motor mount is almost complete to include a mounting location for the two Dyna coils. The coil portion still has alot of work as I need to trim the piece down once the thread bungs are welded to the plate.

Another view of the motor/coil mount.

"

Don't forget to leave clearance for the gloved hands that'll be holding on to the clip-ons.  We check to make sure that your fingers don't get pinched 'tween clip-on and bodywork/frame at full lock in both directions.

Check during assembly -- it'll save time and stress versus getting into tech, having an inspector point it out, then you have to adjust and get back in line.

The cases will be back from NRHS tomorrow afternoon with the bottom end assembled and fresh off of the balancing table. I hope to start final motor assembly very soon.

Finished up the coil mounts this evening and took the bike off of the lift so I could check steering clearances for the steering dampener and stops. I will start on both of the items tomorrow.

The bike off of the lift measures 36 inches to the top of the triple tree.

I talked to Dan the other day and he said to not for get to change the oil!!! He also said that was the first time he had ever been able to finish an 18 pack before he got a motor balanced, but you should still be all right....  :-o  Lookin good tho and hope to see ya there.

Thanks Ray, however I had a hard time reading your post with that rat-dog-demon-cat thing starring at me..........

Thanks for the tip on the Saltx, my bike will get tore down when I get home to actually paint it with something other than the rattle can paint I plan on using give it some color and keep it from rusting.

Stopped by Mr Riches shop Thursday and picked up my front fender. I found the gas take in a motorcycle salvage yard. The tank is off of a 1975 Yamaha DT 100 and with a little work it should fit perfect. I am going to cut off the rear mount and re-attach it to fit the backbone of the bike as well as change out the petcock for a Pingel Race petcock.
(http://i142.photobucket.com/albums/r98/isiahstites/100_1194.jpg)

Picked up this Thunderheader this morning for a $100, I have been watching these on ebay and they have been going for over $350 used. I ordered a collector, megaphone, a bunch of u-bends and tubing yesterday to build an exhaust, but the Thunderheader will get me running incase I run out of time.
(http://i142.photobucket.com/albums/r98/isiahstites/100_1196.jpg)

I finished the brake bracket with the exception of the brake stop which will hold the bracket in a fixed location. The stop will be welded to the bottom of the frame rail and connect to the bracket and will be adjustable to match the axle blocks.
(http://i142.photobucket.com/albums/r98/isiahstites/100_1195.jpg)

Lots of parts have been coming in there just isn't enough time in the day!! There are two things I am running short on.............TIME AND MONEY!!! I have 24 days left until we leave for Bonneville so the pressure is on and it is going to be tight on time to finish the bike. If I don't finish it by August 7th my first race will be Sept 16th at El Mirage.

Please feel free to email, stuff you need, got lots of stuff laying around... even post it here and if somebody has something laying around they are not using im sure they will send it... Every little bit helps... Just when I thought I was getting close last year and about home free, an order to summit for a couple hundred bucks in AN fittings...

Jon,

          I appreciate the offer to help! If you have the Pingel let me know what you want for it and we can work something out........as far as other parts I have just about everything I need with the exception of small things like fuel, oil lines, and spark plugs most of the things I can get here locally pretty easy.

Well I have managed to shed off what was almost a burn out on my part from putting to much time into the bike. I have paced myself and feel like I get more done by just stopping when need be and come back at it fresh another time.

I had to cut off the axle block adjuster and step it out to match the width off the brake bracket.
(http://i142.photobucket.com/albums/r98/isiahstites/100_1257.jpg)

Here is the offset ready to welded in place.

Finished

Got all of the final wheel spacers cut and installed as well as the axle adjustment spacers.

Started to build the tail section today............I spent the better part of the morning into lunch time just starring at the bike and holding up different pieces of tubing at different angles until I found something that was functional yet not completely ugly. Finally this afternoon I figured it out and went to building.

Notching the tubes with my cheap Harbor Freight tubing notcher.

Check to see if it fits.

I have just about finished up the tail section with the exception of permanently attaching the seat pan and the number plates. I have had a few days to look at the tail section and I think it is starting to grown on me..........

I started to try and make the Thunderheader fit and after some thinking I decided I was gonna go ahead and attempt my first set of pipes due to the fact that I spent so much money on the heads. I measured the I.D. of the TH and it was 1.594 and my piping is 1.76 so the bike should breathe a lot better the exhaust I build.

Keep pluggin away at it.  I spoke to big time engine builder here in Fresno and he said to me " I've been drag racing since 1948 and I've never been early on getting my engines or cars done".  So keep on going and you'll be done in no time.  Good luck.

Finished making the front fender brackets as well as trimming, mounting and painting the fender. The brackets were made out of steel strips I cut out of a scrap sheet I had lying around. I welded some round tube to the strips to offset the bracket out passed the fork leg and then bent it back in so it would go around the leg to the mounting location on the fender.

Thanks for all of the compliments guys, it means a lot!

Everyone else that has seen the bike in person or on another forum all like the tank the way it is and it has really grown on me as well. I was thinking of painting it next year and reproducing the paint scheme the same and changing the Yamaha to Buell and the 100 to 1350. Who knows maybe I will just leave it as is.....

Keep the tank just as it is.........always.  More people have seen the bike on the internet
than will ever see it on the salt. That tank is your identity. It's just like using the same
lunch pail when you go from third to fourth grade.
Everyone needs to be indentified and that tank does it for you.
You may have to change it if you go to NITRO.

Thanks Kent, I have so much work to do now that I do not know if I can finish. After B-ville I will definitely be coming down to your shop with the bike to try and find what fits best for a rear and front fairing.

I always appreciate you going out of your way to give me advice and help out with me getting the bike done, thanks!

Piston ring gap.....
(http://i142.photobucket.com/albums/r98/isiahstites/100_1362.jpg)

This evening after I finished with end gapping I tried to put my pistons on the connecting rods and was not very successful. Turns out my pistons are only .002 wider than the end of my rods. After seeking advice from several experienced friends I decided it would be best to have the pistons clearanced professionally. I believe this is the item that is going to keep me from finishing the bike prior to Speed Week due to the fact that I still had some minor fabrication to do to the bike that needed the motor to be in place.

Despite the problem I ran into last night with the piston I kept chipping away at it today. I put the new motor in and set the barrels and heads on so I could check clearance for the petcock to the motor mount and so I could finish the exhaust flanges. I did find the petcock is going to hit the front rocker box so a simple spacer in between the back bone and the tank will solve that problem.

I got the brake mount and stop painted and installed. I had to re-space the brake caliper as I took approx another .020 off of the brake side hub of the wheel and turned down the rotor to make everything straight and true. Also pre-drilled all of the holes for the number plates and will pick-up some 1/4 20 button heads screws tomorrow.

I got a great lesson from Randy at MDR on how to mill the pistons, he finished them Monday evening but I just didn't have the time to install them between work and my busy schedule. So this will be my last post on the bike until we get back from Bonneville. I will finish the bike when I return and hopefully will have it ready for the El Mirage race on September 16th.

My friend Randy(rchop) and I made it back from Speedweek, both with records as rookies. It would be great if that could happen every year. We had a great time at Bonneville and I know I will always remember my first trip with a great deal of significance.

Here is Randy getting ready to run.......he chased the record all week and finally got it on the second to last day. I think we both agree that this picture is probably one of the best that either of us took during the meet. It really captures "Bonneville". Randy set the record for the APS-PG 750cc class to 120 mph and some change with his home built BMW.

(http://i142.photobucket.com/albums/r98/isiahstites/Bonneville%20Speedweek%202007/100_1415.jpg)

Here I am getting ready to ride my way into the history books on Kents very healthy 750 Suzuki sidecar.
(http://i142.photobucket.com/albums/r98/isiahstites/Bonneville%20Speedweek%202007/100_1127-1.jpg)

Receiving my instructions from the starter.
(http://i142.photobucket.com/albums/r98/isiahstites/Bonneville%20Speedweek%202007/100_1136.jpg)

Heading down the course.......
(http://i142.photobucket.com/albums/r98/isiahstites/Bonneville%20Speedweek%202007/100_1139.jpg)

I had a few firsts while at Bonneville, first time to ride that bike, first time ever riding anything with a sidecar and first time down the salt. All were great experiences and I am grateful that Kent was nice enough to let me ride one of his bikes.

I made three passes while at Bonneville all were on the sidecar. My first pass was a rookie run in which I did 137 mph. The record at the time was 135 and some change, I was kind of shocked I went faster than the record on my rookie run. This first pass was quite an experience as I had all of those firsts going on at the same time, almost overwhelming but what a rush, it left me only wanting more and to make another pass.

My second pass consisted of me doing 146 mph and qualifying for the record, had I not short shifted the last gear I may have been able to pull a 150 mph pass. Things were much easier to concentrate on this time like actually riding the bike and watching the tach.

My third run was a back up run for the record. I didn't quite hit the shift points exactly where I was suppose to, but I did have a top speed a 150 mph and backed up the run and got a record. This pass was much clearer than the previous two and I feel that if I had the opportunity to make a few more passes on the bike I could defiantly get into the mid 150's, but for now the record for SC-G 750 cc is 147 and some more change.

So all in all we had a great trip and met a lot of great people that I look forward to speaking with again next year. Thanks to all that helped it is really appreciated!


Got back to building the bike today with intentions of wrapping up the motor this weekend. I started off by finishing the end gap on the rings and weighing the pistons to make sure they were the same after the milling work.
(http://i142.photobucket.com/albums/r98/isiahstites/100_1467.jpg)

Turns out Randy N is a very precise machinist as both pistons were exactly the same and did not require any more work. Here are both pistons on the scale with wristpins, clips and rings.
(http://i142.photobucket.com/albums/r98/isiahstites/100_1469.jpg)

Got everything together and was ready to move on but..........
(http://i142.photobucket.com/albums/r98/isiahstites/100_1471.jpg)
(http://i142.photobucket.com/albums/r98/isiahstites/100_1477.jpg)

I decided I better check piston to piston clearance before I move forward. Good thing I did as the picture shows the pistons do come in contact with on another. Not much but anything in this case is a lot. So I may just clearance them myself and re-weigh everything, if not I will have them machined.

So I started on some other areas of the drivetrain I could finish..........here are the cams installed.

I found out today in order to take apart the clutch pack you need a $75-$100 tool. I have neither the time or money so I made a few things I had in the garage work.

First I took a piece of 4" pipe I had left over from a bench grinder stand I built.
(http://i142.photobucket.com/albums/r98/isiahstites/100_1502.jpg)

 I cut a 2" section off of the end.
(http://i142.photobucket.com/albums/r98/isiahstites/100_1508.jpg)

Set that on the clutch pack
(http://i142.photobucket.com/albums/r98/isiahstites/100_1505.jpg)

I then took a part from my steering wheel puller and set it over that.
(http://i142.photobucket.com/albums/r98/isiahstites/100_1506.jpg)

Set it in the press and very carefully compressed the pack and used a flathead screwdriver and very carefully moved the clip out.
(http://i142.photobucket.com/albums/r98/isiahstites/100_1503.jpg)

This took me about 5 minutes to do from start to finish and I used stuff I had laying around.

Got the new Rivera/Primo pressure plate installed along with the new steel and friction plates.
(http://i142.photobucket.com/albums/r98/isiahstites/100_1509.jpg)

I got the sprockets installed and the primary chain on..............

Post by: isiahstites on September 02, 2007, 12:12:08 AM
I found out earlier this week that the problem was with my pistons and was the manufacturer's fault when the order was placed. So I was destined never to make it to Bonneville with this bike this year after all. Turns out when the pistons were ordered there was an error when the order was taken and the pistons were made with the wrong compression height. They were .187 off to be correct, basically I got stroker pistons. So now we have a new dilemma, no pistons! And it takes 5-6 weeks to get pistons made for this bore. After a lot of thinking I decided I was going to have the heads turned down. This didn't work out either because it is an interrupted cut and the cylinder couldn't be held in a manner that was safe enough to cut it without breaking the cylinder or the tooling. Back to square one, again!

After a call to Dan at NRHS it was decided that they were going to take the pistons out of one of the bikes they are working on and send them to me two day so I can have them by Friday in hopes of finishing the bike and making the next El Mirage race.

So a big thanks to Dan for making this right and getting me a set of pistons to use while my other set are be made.

This looks more like it......the piston actually comes to the top of the bore.
 (http://i142.photobucket.com/albums/r98/isiahstites/100_1517.jpg)

Testing for the squish band clearance, this lets me know how close the piston is coming to the head. I have domed pistons and the head has been cut to match the piston.
(http://i142.photobucket.com/albums/r98/isiahstites/100_1518.jpg)

Squish is in between .0032 - .0035 depending on where the measurement was taken from. I checked six locations per piston. .0030 is the optimum clearance, however I feel good with the clearance I have and not running things so tight.
(http://i142.photobucket.com/albums/r98/isiahstites/100_1520.jpg)

Here is the pile of measured pieces of solder that were not the desired clearance. The clearance is achieved by adding or taking away of base and head gaskets. When I started I was at about .005.
Also remember every time you take a measurement the head has to be put on and torqued down in sequence, kind of a pain in the ass!
(http://i142.photobucket.com/albums/r98/isiahstites/100_1521.jpg)

Next job is to clearance the rocker boxes as the stock boxes will not accept the big valves.
(http://i142.photobucket.com/albums/r98/isiahstites/100_1524.jpg)

(http://i142.photobucket.com/albums/r98/isiahstites/100_1525.jpg)

Finished with one box

(http://i142.photobucket.com/albums/r98/isiahstites/100_1527.jpg)

Tomorrow I will finish the rockers boxes and put in the push rods and bleed down the lifters so I can clay the motor to check piston to valve clearance. If all goes well maybe I can finally button the motor up for once.
Title: Re: My LS bike build
Post by: isiahstites on September 03, 2007, 12:29:39 AM
Got the boxes all cleaned up for all of the new gaskets as well as got the roller rockers installed,
(http://i142.photobucket.com/albums/r98/isiahstites/100_1538.jpg)

Filled the valve reliefs with clay to check piston to valve clearance.
(http://i142.photobucket.com/albums/r98/isiahstites/100_1543.jpg)

Lifters have been bled down and installed and the motor is ready to be turned over.
(http://i142.photobucket.com/albums/r98/isiahstites/100_1545.jpg)

Here is what it looked like after the motor was rolled over.
(http://i142.photobucket.com/albums/r98/isiahstites/100_1548.jpg)

Here is how I measured the thickness of the clay. I have over .100 on the intake and the exhaust was not even close. I also have plenty of eyebrow clearance where the relief gets closer to the valve on the side of the piston.
(http://i142.photobucket.com/albums/r98/isiahstites/100_1550.jpg)

Motor is pretty much done FINALLY! Just need to finish installing the cam and primary cover and anything that hooks to them or runs through them. I still need to install all of the oil lines, ignition, starter, oil tank and make up some spark plug wires.

It did touch Kent, but just barley. Here is something off of there website.

"The piston chases the exhaust valve closed, where the intake valve chases the piston down, so valve float can cause contact with the exhaust valve, but not the intake. So the exhaust clearance needs more margin. The intake clearance conversely is just to accommodate thermal expansion and piston rock."

So an optimum piston would have a tighter tolerance on the exhaust side valve relief similar to what I had on the intake side?? The piston itself is coming with in .032 - .034 of the head depending on where it is measured.

You are correct Kent, the reliefs are exactly the same size. The intake and the exhaust valves are different sizes. As this is my first motor build I have learned quite a bit and am grateful for my new knowledge, however I am at the mercy of others when it comes to certain things until I gain the necessary knowledge. This will be one of the "little things" that I will write down and make right on the next bike I build, thanks Kent.

Nope.  The exhaust valve relief requires more clearance than the intake.  Scott, didn't you say these were borrowed pistons?

the ex doesn't need to be as big as the intake... this is typical of Harley pistons because they can be interchanged from front to rear but this practice is only a cost savings for production purposes... the Harley race pistons i had made were specific for front or fear and had different size reliefs for int and ex.... real race pistons do....

We're talking valve relief depth (piston-to-valve lift clearance) here, not diameter.

Title: Re: My LS bike build
Post by: JackD on September 03, 2007, 10:41:45 PM
Proper clearance for the radius of the valve and depth of the pocket are 2 of 3 considerations.
Valves tend to not follow the dimensions observed during setup that addresses material expansion, flow, and hot spots that can produce detonation.
Valves will actually close twice during a high speed cycle because they bounce up off the seat a bit when the weight and speed exceed the springs ability to hold the undampened (float) event.
Lighter weight in the valve train and stiffer springs raise the level before it happens , but it is at the expense of the system.  :wink:

Yes, but they were what I was supposed to get from the start. The guys I bought them from made it right with me with some other parts I needed and ordered me a another set with the right compression height because I had originally ordered two sets.

You now have me wondering about why the exhaust barley touched, I know it requires more clearance than the intake valve, but my intake and exhaust cams both have the same lift. Is the exhaust valve seating deeper in the head than the intake??

I think it has to do with the orientation of the cams, however I am not sure.

well nick i was talkin pocket size.... as in way to big... now that you mentioned it... over .100 is way to much depth.... even for an exhaust.... and in an area of about 1/3 of the combustion chamber size... giving up way to much compression.... sheesh your acting as if you made these pistons.... did ya? oops i'm sorry i'm being meen again.... i didnt mean that, heck even your web site says you don't make pistons you just farm them out. You just design them. I'm curious and since you proclaim to be a piston expert.... what should the pocket size and depth be for a 8000rpm push rod motor with what was suppose to be race pistons, race cams, and race springs? lets give the newbie some assembly advise......

  Scott,

  That's a nice looking project you are doing! The exhaust system is really a sanitary looking system. It sounds like there is some questions on the valve clearances. I didn't see anything about checking the valve events with a degree wheel and seeing if it agrees with the cam grinders specifications. If you haven't, I'm sure Kent can give you some advice on doing that.

  Good luck at El Mirage. I enjoy your posts.

Scott-
I was curious if these pistons were off-the-shelf generics or were they custom built for your specific application (valve diameters, cam timing events, etc.).

Yes, on most two-valve opposed cylinder heads, the exhaust (EXH) seat is located higher in the chamber than the intake (INT).  Regardless, sometimes the piston designer dictates the INT and EXH reliefs be symmetrical so you can interchange pistons if needed.  If you're seeking very high compression then individual diameter and depth INT & EXH reliefs are required.  Looks like you have symmetrical relief pistons, which are fine as long as your compression requirement is met.

The piston designer's job is to collect as much information about your setup and provide a suitable set of slugs, considering all of the eccentricities of an internal combustion engine.

Since I am new at this and still learning I left the complete design of the motor up to NRHS and I am happy with them and their customer service. There have been a few mix ups, however there has been max effort on their part to make things right. In the future with all that I have learned and all that I plan on learning I will be able to do a custom race piston. For now I will be cautious and continue to take small steps and ask lots of questions.

I always give someone a chance to make things right instead of publicly blasting them online like you see far to often on internet forums. Even thought there was a mix up on the compression height of my pistons and it was not NRHS fault they stepped up and pulled a set of pistons out of one of their bikes using the same set-up. That is great customer service in my book.

I preformed the leak down test today and it was 0-2% on both cylinders? Is this normal on a fresh motor? I was expecting there to be a lot of air past the rings since they are new and have not been run. I was expecting after I have run the motor a little for it to tighten up once the rings set.

I had to raise the back of the tank a little bit to give me some clearance to keep the petcock from sitting on the rocker box.
(http://i142.photobucket.com/albums/r98/isiahstites/100_1554.jpg)

Here is the clearance after raising the back of the tank.
(http://i142.photobucket.com/albums/r98/isiahstites/100_1555.jpg)

I got the intake, carb, fuel line and velocity stack installed. I am not sure how much I like that stack sticking way and the hell out there, but it is gonna have to do for the time being. This was a pain in the ass job as I had a hard time with the intake and the new seals.

I got all of the sprocket, trans and clutch bolts torqued down to specs. I finished installing the primary cover, adjusting the chain tension, adjusting the clutch and installing and adjusting the foot shifter.
(http://i142.photobucket.com/albums/r98/isiahstites/100_1569.jpg)

I installed the new higher flow oil pump and installed all of the fittings. Also figured out the whole oil system so I can run the lines tomorrow after blasting the oil tank and painting.
(http://i142.photobucket.com/albums/r98/isiahstites/100_1570.jpg)

What are your thoughts on the velocity stack over a conventional air cleaner?

Scott
Title: Re: My LS bike build
Post by: JackD on September 08, 2007, 08:21:36 AM
The stack on the dyno will give a good result in static air and is just another tuning variable along with all the other parts on the way to the end of the exhaust pipe.
Moving air past the end is quite another story and that is where the tear drop can capture the air and direct it into the carb bore.
 It is not an air cleaner at all , but a flow correction device that has a lot of thought put into the design.

         As long as I do not run into any issues I should have it there Sunday morning with the intention of making some shakedown/tunning runs. If everything goes good I will hammer it in October.

Going to the garage now to finish up the misc stuff (the last 10% has been more work than first 90%) and I hope to start it for the first time this evening.

Well I got all of the wiring done and most of the small stuff done. Here are a few pics of the exhaust being painted with some high temp rattle can stuff that ended up looking way better than I ever thought it would. The pipes look ceramic coated.

(http://i142.photobucket.com/albums/r98/isiahstites/100_1591.jpg)

Tonight I fired the bike up and man is it loud! It fired right up and ran for a few seconds and died..........now I can only get it to fire with the enrichener and same thing it will run for a sec or two at most and die. When it does fire and run for the short time it sounds real healthy and dies just as fast as it started.

So to this point I have checked the petcock for flow, checked to make sure the float bowl was getting fuel and checked the main and intermediate jet for any clogs or debris and everything appears to be good. I am running a dyna 2000i ignition and feel the timing is correct, I feel the problem is with in the carb as I can not see any fuel sprayed into the carb when I twist the throttle open. I am running a S&S D with a Thunderjet.

It got late here quick and everytime I would fire it off I think I scared all of the dogs and cats with in a square mile. So tomorrow I will get to troubleshooting the problem on a fresh mind and hopefully get the beast to idle.

Post by: isiahstites on September 16, 2007, 12:57:57 AM
I got the bike figured out this afternoon! It runs, it runs!! The problem was that I wired the coils in parallel like I have always done not realizing that when I bought the coils six months ago that I bought lower resistance coils for the race application, these need to be wired in series so the ignition was trying to protect itself by shutting down since it saw 1.5 ohms instead of the 3.0 ohms it was looking for.

 I still need to make adjustments on the carb and the timing. I will do all of these changes on the dyno hopefully next week sometime. I am taking the bike to El Mirage tomorrow to have it inspected in preparation for October's meet. I have decided against running it tomorrow because I was not able to tune the motor at all. I will get a good tune in it in the next week or so and be ready for October.

For those that have asked in the past about the riding position, here is a picture of me testing to see if the tach is located is the optimum place.

I remember when I was a kid I had an old honda xr 80. My buddy had the Yamaha 100 that tank came from and it was so much faster than my bike.....I was green with envy because it was a 2 stroke, was faster and had better shocks then my little Honda.

I still see that tank and it brings out the "I gotta have one" emotion even after all these years.

I know you will likely paint it, but I hope you dont.

Great bike.

Well I made it out to Elmo today to have the bike inspected. Everything went well and I only have to change one line on my carb from the Thunderjet (an oversight on my part) and I was given advise on a few other items, but all were said to be safe and would pass inspection. So this month I will get the bike tuned and maybe even go up to Elmo and run it in preparation for October's meet.

The gas tank seems to continue to create controversy, people either really love it or they want to see it painted as they like the shape and say it goes well with the bike. The Yamaha tank was definitely a conversation piece for a few people today whether they loved it or hated it.

Hear are a few pics.......

October El Mirage meet.......bike is running really good and I will be ready.

Unfortunately I did not realize how cool it was going to Bonneville with this being my first year. So I took almost all of my vacation time to go to Speedweek and am now stuck with wishing I could attend the Finals event. So next year I will not spend as much time at Speedweek so I can go to WF's as well.

Got the bike on the dyno for a short time today. We made a real soft first run just to make sure everything was good with the drivetrain and the new motor. All went well and it was clear the bike was on the rich side of things on the main jet. We didn't make any changes as it was more of a shakedown pass then anything. We made two more passes and had some problems with the sniffer/gas analyzer so I couldn't make any changes and then be able to see the affect they had.

So all in all I am happy as I found out that all of the motor/trans work I did held together on the dyno. Checked the hp on the last two passes and both were 110 rwhp @ 7000 rpm with a great power curve that had no dips or spikes in it at all and created power nice and steady all the way to the rev limiter. I have the rev limiter set at 7000 rpm, but may play with it after some research on what will be a safe rpm to rev to without blowing the motor.

We fill that once back on the dyno after it is repaired and some jetting changes, playing with timing a bit and maybe the rev limter we may be able to pull another 10-15 + horse out of the motor.

So for just setting up the motor in my garage by sound and throttle response I am happy to this point with the 110 horse out of the little 82 cubic inch motor.

Ok, I finally got some video of the bike today. I bled the brake today so I thought I would take it out for it's first run.

Video one is 1:37 long and you can really hear how good the bike sounds and video two is 1:50 long and was added because it was kinda hard to see the bike with all the cars parked along the street.

I have'nt done much work to the bike lately as I have kinda been taken a break, however it is almost 100% race ready. I still have to do some small minor stuff to finish along with saftey wiring the bike.

I got the air/fuel analyzer working on the dyno and made a few passes this evening. I am still on the rich side but getting closer. I had a nice big dip in power around 6600 rpm and it came back on strong after that so tomorrow I will mess around with that and try and figure it out, I need to read up on my Thunderjet as thinking something may be happening there. After I get the air/fuel right I will move onto the ignition and hopefully be done tomorrow afternoon so I can get ready to go to the race on Sunday.

As we stand now it as at 114 horse at 7300 rpm and if I recall correctly around 90 ft tq give or take and about 12-1 a/f.

If all goes well tomorrow hopefully it will be in the 120's.

I''d shoot for 13.2, but it won't matter what the dyno says, as soon as the wind starts, the actual mix will vary.  Maybe your stack should face forward....
Best place to sort it out is the little brown or the big white dyno, unless you put a blower on it...

Re: stack orientation
If you're going to use an open stack (I wouldn't) a stack with its axis 90° to the wheelbase will have a slight siphoning effect as speed increases that will change the mixture slightly. I have a feeling that it's not linear though, but has minimal effect below X mph, and a sharp increase - but what "X" is IKBA.
A forward stack (although obviously a dust, small bird etc. vacuum) will only experience a slight pressure increase as speed goes up, but as long as the air correct is inside the stack it's harmless.
My choice is the surround a 90° stack with a large volume air box ending in a sized forward entry. Near side of the box is flat, and sandwiched between the carburetor body and the stack flanges.
Remember that any jetting you develop will need serious tweaks for elevation.
Looks like you have more than 1 Thunderjet in there? Not to confuse you but if there are more than one they need not be mounted at the same distance from the throttle shaft, not at the same depth from the wall, and not the same jets sizes, etc. In general, the farther from the wall the earlier it adds mixture in the RPM range.
If after lengthy testing you have a flat spot that you can't get rid of, I would consider making the primary length adjustable since you've nicely made them parallel (you can buy swedged short pieces, just cut-n-insert). Remember your tuned length will be different at the salt due to air density, air temp, etc. anyway.
If you get to this point, the final position of the collector can be moved a bit. It won't affect the tuning, but angling the collector up so that the exhaust aligns with the trailing edge of your aero shape (probably your gluteus maximus), and inward to the tire centerline reduces your drag somewhat. If you do the math first, you can rotate the collector on the stub and angle it up and in with 1 cut (although I would prefer a 3" radius bend here).

As was stated, I don't think your frame is stiff enough (no comments!) - I don't mean it will break, I mean it may not be as stable as possible given the geometry. Much of the general design doesn't lend itself to easy changes, but 2 pieces easily made with your notcher will improve an obvious weak link: the drive side. Here's the idea:
(http://victorylibrary.com/graphics/Paughco-Sportster-LSR2.jpg)

The angles need adjustment. The vertical evenly divides the span lengths of the 2 rails, and the horizontal goes from mid-height back to the axle plate. Same OD/ID as frame.

I got as far as I could this afternoon on the dyno. My final number were 122.7 hp and 95.5 ft tq. I got rid of the dip in power at 6600 rpm by tightening up a loose connection on one of the coils. That was not the only thing that loosened up and had to be tightened......dam Harley's! I got the a/f as close as I could, it is about 13.5 at 4000 rpm and slowly tapers to about 12.5 +/- as it gets to redline at 7500 rpm. I could not get the a/f as good below 4000 rpm because the bigger intermediate jets I ordered are back ordered. I drilled one intermediate out to .041 which helped, but did not completely fix the condition. Good thing is once I am out of first gear the motor should not see to much of 4000 rpm and below. I played with the timing a little bit and got a few extra horsepower out of the motor, however I may have got more if I would of made a few more passes.

I feel there is little bit more hp and tq in the motor if I did some more fine tunning, but it is good for now. I definately feel a good experienced dyno tuner could exceed what I have done as I am just a rookie tuner.
For now I am very happy with the numbers and all that is left to do is race the dam thing!

Post by: isiahstites on November 12, 2007, 01:33:03 AM
My first run was good and exactly what they wanted out of a rookie inbetween 125 and 150mph. The bike pulled extremely hard through first, second and third gears! I was really suprised at just how hard the bike pulled. In 4th and 5th around 7000 rpm the bike started breaking up and at this point I believe the thunderjet may have added to much fuel at the higher rpms as it is vaccum operated. So my one and only pass for the season was 128 mph with a really rich tune in the bike. I made the neccesay jetting changes in hope for a second pass. I felt if the bike ran as good as it did in first, second and third and could do the same in fourth and fifth that It would make a 150 pass with no problems.


After a few of the Roadsters blew tires and had some spinouts on the course they deemed it unsafe and stopped all second round runs for Saturday in an effort to move the course over. So I would have to wait until Sunday morning to see what she really has.

Well we got up early this morning and got to the track at around 7:00 A.M. so I could get a good spot as the air is better in the morning. I was 4th in line and attended the drivers meeting at 8:00 A.M. where all the driver were told they may cancel the event due to the ambulance not being able to be on site and that they did not want to take any chances with anyones saftey. They relayed to us if they could not contact an ambulance by 10:00 A.M. that they were going to call the meet.

Well around 9:45 A.M. an ambulance was on site and everyone was excited to get the race going until the wind decided to pick up...........they cancelled the meet at a 11:00 A.M. and we packed it up and headed home.

On a side note the bike was very steady at speed and I did not even notice it was rigid. The bike accelerated hard and the brake worked good. I couldn't of been happier with the overall performance of the bike top to bottom. With some tuning we will be back stronger that ever next year. After my run Cami said to me she was really proud of me for going that speed. I said thanks and didn't think it was such a big deal until she reminded me I had built that bike from top to bottom. That I had turned every nut and bolt and made everything work together.........it was at this point I smiled and thought wow I built this bike and it worked! That was a great feeling..........

Sooooo, what did you run Scott? Oh, yeah, I remember. You really think a jetting change would get you 25 mph huh. I guess we'll never know, too bad.  :-D  You need to bring your wife everytime. That way we have someone cute and personable to talk to when we're leaning on your truck.... :-D

       Larry    #591  pedaled it thru for a 152.465

PS: Did you hear who won the pool?

Listen, don't fret about a little dust in the motor.
Next time take the rag out of the stack and you will be amazed at the improvement.

Well this is fun, I guess we need something to keep us occupied for the next six months.

They don't call me "Big Scott" for nothing, but hey I wasn't gonna say anything I dont' like to brag. Unlike yourself I find it hard to find time for masturbation, but then again if your name was "Big Larry" you probably wouldn't have to worry about masturbation. :-D

Lest any of you think I'm not keeping up with my duties, please understand that while I'm the "Potentate of Porta-Potties" at Bonneville -- I have nothing to do with the little houses at El Mirage.  If they were out of tp -- it weren't my fault.

When we turned in the rental vehicle after World Finals the rental guy asked why I had a couple of rolls of tp and a few pink "breath mints" in the back seat.

Okay, everyone, back to work.
