with four months until we need to crate and ship the across the pond-with parts still appearing from all points of the compass-the one off parts piling up fast-and way too many other builds taking up time , dave [buzz lightbeer ] and myself thought it high time we added a few pictures of how things are shaping up-
-
the bike has been in my ownership for about twenty years-and has variously been powered with 750/1000/1100/1170/1260 motors , all aircooled suzuki , it has been street raced , drag raced , bracket raced , impounded and fallen off of , all over europe , so when dave suggested we build a proper old skool aircooled multi - i had a lot of parts to throw in the mix-
dave has called on his many years of drag racing and metal fabricating to bring some great sponsors to help the bike - [mostly from the usa]
this has helped us a great deal in getting parts at sensible money , as to build something like this from locally sourced parts would be prohibitive.i am lucky to have the keys to AIRCOOLED WONDERLAND-which makes stuff like cases , cranks, heads etc-plentifuel.
the bottom end of the motor is gsx1100 EFE[1135cc]-the toughest out there , to this we added a *DAVE BRANCH* -england- pro mod/funny bike crank , an *R & D* -florida- transmission , and a WISECO 1327 big block -we used a GSX1100ET[1074cc] cylinder head [the earlier heads have deeper port floors and dont require resin building] this head was fully skulled by MRE-
i will let dave write up the full spec of the motor-
the first two pictures are with our mock up motor,and setting ride height,rider posistion etc.
-
while dave was left in sunny england to work out the science , and blue glue the frame together how we wanted..
-
i had to race this potent triton in rain soaked france-dave was left alone with some choice goodies to keep the bike happy-
-
we have both tried to use the best parts we can lay our hands on to get this 29 year old , blunt instrument down the ghreat white dyno
in the fashion were used to-
i have to say the R & D MOTORSPORTS transmission , is really a work of master craftsmen , it deserves only the best 10w40-
i,ll let dave describe the cylinder head..im bound to get carried away. :-P
-
Oi thats my bottle LOL CCMF!!
-
As BBK has started the build diary, here is the spec of the motor.
1327cc forged MTC pistons now machined to 12:7 to 1 static compression, Wiseco bigblock with LA Sleeves O'ringed , GS11OO ported bronze skulled head, with 31/26 Ferrea stainless valves, Kibblewhite valve springs with GSXR1100 rockers & Megacycle cams all the head & piston work has been done by Jeff Reel of Reel Race Services it flows 140+cfm. The head was supplied by Jay Reagan owner of MRE, who also supplied & prepared the bigblock for us.
GSX1150 crank & clutch with straight cut primary gears, both prepared by my friend Dave Branch of DB Engineering. Dave also made the belt drive alternator bracket for the bike to.
Kevin at Lectron Fuel Systems personally built a set of 44mm powerjet carbs for us, once he knew the spec of the engine.
Mark at R&D Transmissions fully prepared the gearbox & shift drum using ceramic bearings supplied by Big Dave at Worldwide Bearings.
Dawson Motorsports have supplied us with a top end oiling system, single stage lockup clutch, dyna ignition, pnc300 nitrous controller & all the nitrous components as well as many other parts.
We have converted the the chain & sprockets to 530 pitch instead of the extremely heavy original 630 pitch
A lot of the engine components have been DCT'd this includes the crank assembly, camchain, final drive chain & split links these are actually being shipped back to me on Friday.
-
the beginning of the project
-
As you can see in the previous pic we had a shock absorber offered up, but in the end we have gone with a rigid set up.
Here are some more pics
-
Are you sure? Good suspension is the key to eternal hoppiness.
-
i had to race this potent triton in rain soaked france-dave was left alone with some choice goodies to keep the bike happy-
Life is tough isn't it?
-
Wobbly, the reason for going rigid is that to put all the bracing & mounts in for the shock linkages. It would mean a hell of a lot of work removing some tubes & replacing with thicker wall tubes. Plus the shock absorber would have taken up vital space needed for the nitrous system & bottle, these old frames are very restrictive to try & fit everything in, unlike my dragbike with its bespoke frame
-
heres a pic of the frame stiffener
-
another of the stiffener with the old weld ground out
-
Buzz,
The struts you are using to replace the suspension look a little on the weak side. If your bike weighs 600 lbs fully loaded, then there will be approximately 300 lbs at the rear wheel. Your struts are somewhere near the middle of the swingarm, therefore the load will double to 600 lbs. Because the struts are not vertical, the load will again be increased. The struts are considered long columns. Long columns fail by buckling, usually without notice once they start to deflect. I can't tell you what size you need, but am just cautioning you to consider these struts more carefully. Any structural engineer could do a quick analysis and tell you if they are strong enough.
Tom
-
tom, those aren,t our struts-just mock up blanks to set the ride height to suit the riders-
considering how well fed i am , and plan to continue to be so-our BSW struts will be a lot more subtaintial- :mrgreen:
check out the drag bike buzz built above , says more than i can here. :cheers:
-
Headlight & rev counter mounting on the headstock
-
The headlight/revcounter bracket, this will also have the coils mounted on it as well. The reasoning for this is that they will be away from any electronics so rfi won't cause any problems.
-
Revcounter mounted

more
-
Another view with the headlight mounted
-
love the looks of a traditional BLUNT instrument-
-
Tom, here are the proper struts we are using. They are 21x31mm solid EN24T & the top mounting bar isd solid 22mm EN19
-
Struts look much more substantial now.
If you don't mind me rambling a bit, I'll tell you what I don't like. I look at that humongous gas tank and think, "That thing's in the way - - can't get my upper body and head down very low." Then I look at your nice instrument mount/ "headlight" and think "that things in my sight plane, especially if I make a special flat gas tank."
Just thinking out loud. A lot easier to make changes now than later.
Tom
-
I know what you're saying Tom, but we want it to look like a stockish looking 1980's Suzuki GS1100.
If we was building an all out saltbike it would be a lot different, but we like 1980's aircooleds both GS's & Z1's. Now if I take off these rose tinted glasses :-D
-
Buzz,
Are you running "M" class or "A" class? Length of swingarm may make the difference (more than 10% increase in wheelbase will bump you into "A" at SCTA; not sure about BUB/AMA).
I don't blame you for wanting the traditional look :cheers:
Tom
-
Re swingarm, as Tom said 10% for SCTA and with BUB, if you build it from the stock swingarm it's ok. If you build it from scratch it makes you A. That's what I was told when I asked. Also, if you run A in SCTA, forget about the headlight, cuz you can't run one. I'll second the vote to change the gas tank as well. Good luck. :cheers:
Larry
-
Tom, Larry, the arm is a standard Suzuki arm with extensions so I will have to have a measure up, is that +10% of the original wheelbase?
Granted the fuel tank ain't pretty, PJ has another one with the back cut off to follow the frame tube so will pick that up at our meeting on the 28th of this month & see what that looks like, thanks for your help & interest.
Dave
-
SCTA 2012 rule changes are listed on the "news" section of the landracing.com home page. Scroll down to new rules, then click on "more". New frame rule reads as follows: "A maximum wheelbase not to exceed the original OEM specification plus 10%. Entrants shall provide acceptable documentation for record certification."

Hey Lightbeer,make a tube tank with just enough room for a runs worth and then make a mock tank out of rubber foam exactly the same dimensions as the stock tank....that way it looks original AND you've got something comfortable to rest on while in the racing crouch.....
That's OK, thanks :wink:
-
Tom,Larry, I had a measure up of the wheelbase today. Stock wheebase on a 1980 Suzuki GS1100ET is 61" therefore +10% = 66.1"
With the wheel fully forward in the arm its 65.1/2" at its shortest & 70.1/2" at its longest.
Hmm.. decisions decisions, I will check out the final wheelbase when I finish the engine build, then I can put all the combinations of sprockets on as I need to sort out the chain length as well.
Dr.G,n I can see your point, but we will run that ugly old tank:-) or maybe the one with the modified back.
-
According to my math (the old math), 61" plus 10% = 67.1", if it will help.
Tom
-
Tom, you know you are right, that old math is correct. It must be the new European metric math over here thats wrong :wink:
-
incidently , and of no use at all -the metric system is older than the imperial system. :mrgreen:
-
Hey Buzz,
Bike looks great. AND I love the fact you want to look somewhat factory. I myself am building an aircooled GSXR for A-AF class for 2012. based on 89-92 GSXR. I have been modifying my tank so as to get down lower. so far so good. By the looks of yours, I am assuming you are running 1350cc class?
Are you running gas class or fuel? If gas class make your fuel cell to hold 7qts or more,because you will have to go back and forth to fuel station just to run it. real pain in the butt, thats the rules. I decided to run fuel class just so I can bring my on flavor Q16 VP is my choice,also figure corrected elevations 7700 ft or more if hot.
-
hey marty, the gixxer sounds good, the real trouble with keep going to the event gas station is you end up eating several punds of the homeemade beef jerky that,s on sale there-mmmm cant wait... :mrgreen:
-
Thanks Marty will you be at Speedweek this year?
Here are some more pics of the build footpeg/gearlever
-
Here is the card template of the airbox which is 4 piece, so it can be taken apart to get to the Lectrons. There will be a 90mm diameter inlet tube on each end of the airbox.
-
This is the sprocket carrier which has had 8mm machined of the face to bring the sprockets into alignment
-
Here is the front fender with a mocked up extension to stop salt spray covering the motor, it will have a lower brace to stop it flapping around
-
This is the end can for the exhaust, just got to mock up the intermediate pipe between headers & this can
-
Here is the can
-
The modified tank got delivered & it is fuglier than the original tank:-D so the fugly tank stays.
It will sit in the original place rather than jacked up as it was in the earlier pics.
This is because to run in fuel class we need to shut the fuel tap off from the handlebars, so we will use an electric fuel pump. By using a pump we don't need the Pingel fuel tap fitted to the tank, so this allows it sit in the correct place rather than jacked up to clear the airbox.
-
I reckon the airbox should detract attention away from the tank a bit did you get the idea from volvo!
Function is what counts dude good on ya
Oz

No it looks like a bread bin my mum had :-D :-D :-D
-
EPA exclusion granted on the bike :-D
-
fitted pnc 3000- fitted dyna 2000-fitted wideband controler and connected-mocked up nos solenoids,high and low pressure fuel pumps-ran cables-mocked up containment-fitted arming switches-dismantled bike-loaded into my landrover so i can do a number of machineing jobs and wire the bike-drank some ale eat some curry-had some laughs -drove 4 hours home
-
Well it looks like you're OK for wire there PJ!
Looking good; see you next week.
-
wire saved from the scrap-with prices where they are that,s a tough decision!
set a few parts up in my lathe and mill-if there,s one thing i cant accept- it,s mixed threads.-on a japanese motorcycle all threads should be METRIC-so all non metric threads were machined out and either re-tapped with the right size fastner-or time-serted.
the metric fastners required counter boreing to allow the cap heads to sit flush-meanwhile, some nylatron rod was notched on the mill and bored to take the M8 fastner that will hold the headlamp binnacle in place-in here sits our coils, oil cooler, NOS and IGN arming switches and the tacho.various shiney parts [yokes, engine cases , alternator mount etc.] were media blasted and the shine was removed,we,ll either laquer or paint these parts.
with a big rush to get the frame back to the south coast for final welding and some paint,this left me with most of the wiring loom to lay up and finnish,the font of it is done,and the rest will be terminated as soon as the frame is back from the paint shop.
-
been awhile but here are some more pics of the build, this is the exhaust mocked up to get the pipe angles
-
The new exhaust pipe bend, this will be finally fully welded once the engine is fully built & fitted into the frame. We will be using a twin lambda sensored air/fuel meter, which will be used to set up on the dyno & then when we get to the salt, checked again to see if we need to make adjustments to the carbs
-
Here is the oil cooler offered up to fit into the headlight shell, & then fitted into it
-
Good man wondered why i hadnt heard from you this week you have been busy!!!
-
More
-
Some paint
-
Paint again
-
Frame toshed
-
Here are our primary sponsors logos airbrushed onto the bottom of the fork legs
-
spray on stickers-unreal what they can do these days-
-
got driven down south to do some work on the bike-before i went i did some more blasting and machineing-
-
the frame has been done in a 2 pack gun metal grey, which was a yamaha paint-
the spaghetti western is still in full flight , with more and more components to find homes for - and work out how they function.
we also started to mock up the two fuel pumps , and all the associated pipe work.
the fuel and nitrous lines have been cinched up , and we are finally starting to see where all the parts will live-
we still have to get paint on a few parts , but as soon as this is done we can get it built up and start to fit parts fully in place.
we hope to be on a dyno in the next two weeks-
-
this is pretty much how far in we are-
-
here,s the frontal , which i dont think we covered-been helping team page with some basic alighnment issues they had on there 1969 triumph-after around eight hours measuring and machineing i think they are back on track-
dave and the paint/body guys have re-worked this front mudgaurd so the rear section is way longer to cut down on spray-dave is donating body parts to fill the hole....
-
more-we gone to a lot of effort to keep it as stock looking as we could,as these are the bikes we grew up with and like the looks of-
-

Kelly, the Triumph has a strong fork and front end. The swingarm and back end are beefy too. The frame betwixt the two is relatively flexible. Sometimes this can make for interesting handling. The frame flexes a lot more than it would with the more supple and weaker original equipment front and rear. The cure is a stronger frame. This might not be a problem. If it is, this would be something to consider.
Those bikes look good.
-
WW-thanks mate-i agree-i did many miles as a kid on a oil in frame bsa which was about as close to perfect handling as i ever had from a twin-there,s a few things i would have done differently on the triumph,but it,s not my bike,so im just helping the guys get things right with some alighnment issues and some machine work etc-my fee-i get a ride at BSW-ride a bonneville at bonneville- :cheers:
we all have 22 days left before we have to button our babies up into the container to skip accross the pond and come and join in your fine race meeting-
latest few pictures of our ride-
-
back down to the southcoast asap-got a wedding to attend then it,s final build time-dyno and road test-luckily BUZZ has access to an airport service road.
-
Well one of our sponsors has built us a website for our salt adventure, there is still updates happening to but please check it out.
We will see you all real soon, that fever is getting real bad now :-D

bike has landed in new york-then onto a freight train to L.A. longbeach-it,s gunna go right past the salt!!
here is our dyno video-175 rwbhp all motor. http://www.youtube.com/watch?v=_J4LOR-rX_E&feature=plcp
see you on the white side-

That is a lot of power for an NA engine of that size. Be careful.
-
interesting build, luv the old skool stuff, 8-),,, on my first trip to Bonneville i also noticed the same as you, no big air cooled Kawasaki or Suzuki's,, will be watching your fun at the salt, :cheers:,,
we got a fella here , lives in Brisbane, who builds carburated EFE street bikes(no niterous) that will run the quarter in the high 8 seconds,, 1500 and 1800cc,, have often though of getting one built to run at Gairdner, :-),
-
Hey BBK, is that casting stock stacked in the background of the shot of the bike ? ? ?
-
Yep Doc it sure is, anything alloy he finds lying around cannot be resisted :-D bit of a magpie is our BBK

hi bo-175 bhp is about right for this spec-a lot of care went into building the motor and we got the whole mess D.C.T.,d-fingers crossed!!
cant wait

love rthe fact that at every drag race you see the modern pointy skirtsbike bodywork pulled off and 8 times out of ten it s a real muscle bike ie AIRCOOLED.1800cc right on the limit of the stock cases-great work-
we look at brett de stoops work and just love it! aged iron!!!
-
Hey BBK, is that casting stock stacked in the background of the shot of the bike ? ? ?
yes well spotted- i love lookin into other folks sheds!! mo0st of this is leftovers from drag racing/moto-x/off road destructive days-
i have a second batch of high silicon ingots from pistons-
plan is to make a cylinder head for an old bike-
-
well we had a blast-best speed was 164mph , just off the power and a wandering misfire-we lost compression on the last day but both got our c licences -so not too bad-met up with some old pals and made some new-
watching my mates ashes being spread down the salt was hugely emotional on top of all the emotion that goes with speedweek-
as ever wanted to thank all the scta members and all the volunteers for so much hard work and so much dedication -all so we can travel thousands of miles and hurl ourselves down your wonderful salt flats-
THANKS -SEE YOU SOON.
P.J.

It is great that you had a good time. Hopefully there is nothing seriously wrong with the engine.
