We're getting ready for El Mirage. I'm prepping the M frame for the 650 A-PF class. The record is 145+mph, it is in the book since 1995! There is no M class at EM but this bike is fully M -PG compatible at the SCTA and AMA.
The frame is a stock '50 Triumph Thunderbird, the engine is all alloy with a modified unit type head. I will be using AMAL GP Carburettors.

Bew-Ti-full :-D Trumpy Alp, I hope you nab that record this year,,,

Looks fast.................with room to lower your butt maybe an inch, and your hands by several inches :-)

Thanks Tiny,

Old Scrambler,
Yes, A class allows me to lower the seat and handlebars but I will maintain the current M class set-up. I wanna shoot for the M-PG and M-PF records at the AMA Bonneville event.
My best on this bike was 131.993mph in November 2013 with a 650 M-VG, same pre/unit combo but with a ironhead and iron barrels.
Picture of 650 M/VG 130.308 mph return run from August 2013

The AMA M-Class allows for the bottom of the hand-grips to be no lower than a horizontal line at the top of the rim................same for the top of the seat at rear rim.
Yeah..............the 145-mph looks so tempting :-)

You're right (thumbs 10" apart as well) and I will keep it M class compatible.
EL Mirage is next week, hopefully it won't rain. I'll keep you posted on the results.

At El Mirage Nov 2014, the little bird went 130.734mph with no fairing but got the record in the 650cc APS-VG class.
-
I always liked how cosmetically simple your bike is, with a balls to the wall motor. Very cool stuff. Good luck at El Mirage! :-)

First race of the season and first record of 2015 with our stock 1950 Triumph frame!!
We broke the 145.9mph "Tatro Machine Special" fuel record from 1995 with a speed of 149.279mph. Now we are also the worlds fastest 650cc Fuel bike with a pushrod engine! With no fairing/blower/turbo etc.. "A/PF" class but with a M bike due to El Mirage not having M class.

Congrats. Picked up a good 19 miles an hour. that's something on itself.
Plus the record.
what did you do to pick up all that speed? What fuel are you using?

I changed the timing, redesigned/built a new head and used alcohol mixed with some nitro.

Alp; I bow my head and duff my my cap
in respect to your bike and what you do.
Brilliant

Just awesome.
Way to go man. :cheers: :cheers: :cheers:

Thank you!!
Our other Special Construction "A-VF" bike had gearbox issues, we will give a try on that class record next time. But here is a nice image of our A-VF bike from the SCTA facebook page.

Old Scrambler Thanks,
We have some plans set for August and I already figured out what classes to run at the SCTA Speedweek but I couldn't decide on a class for the AMA Bonneville event. Maybe somebody can suggest a class. We do not want to run in a open class.
For Speedweek I registered for the 650cc A-PF class, according to the rule book the record belongs to Marc Leininger Honda with 134.849 but we will aim for 156.389+mph which is that same bike's APS-PF record.
After we get the record or destroy the engine we will switch to the 650 A-VF class and try to get the 144.531mph RPN Motorsports record.

Great meeting you last weekend Alp. And congrats on the record, very well done.
See you in July

Both of our 650cc Pushrod and Vintage engines are almost ready for Speedweek.
SCTA will make an announcement within the next couple days, we're keeping our fingers crossed! This is from the latest BRN

Getting the A bike ready for the SCTA Mojave Mile,
We will tune and do some testing before the AMA event.The ultimate goal is to get the fastest 650 Special construction record including the partial streamlines.

And I plan to be at the BMST to see it happen!

Tom..............I'll watch with you 8-)
Very cool build.............

it is official, our little naked 650 pushrod is the fastest, includes all a-partial streamline 650/750 and 750/1000cc a-pf bikes.

Congratulations Alp! By my calculations, your motor must be putting out somewhere around 110 hp, over twice what mine has.
Tom

Awesome!!!!!!
Well done.
I must say it looked the part when I first saw it. :cheers: :cheers: :cheers: :cheers:

Congrats to you and your team.
That is some high speed for that engine.
Period.

Congratulations to you and your team!!
Great job.
110bhp from 650cc's = 169.23 bhp/liter, that's F1 territory . . . . . .

Thank's everyone.
This is the first time the SCTA is organizing the Mojave Mile. All our friends from Europe/Japan and Down Under told us that they had a blast, we are thankful to the SCTA and all the volunteers for creating such a professional event within less than 10 days.

Bud Hare:
169.331 record (2-way average) on unblown, pushrod 750cc Triumph on fuel, special construction with center steering front end, at Speed Week 1969
You are closer than any of the rest of us ever got! I think you should be able to do it on the longer salt course.
(actually, Don Sliger did a single pass at just over 170 on an unblown 700cc pushrod Enfield on fuel (drag style frame) but never put the two-way record above high 150s.) Those are the fastest pushrod runs I can remember, though there might have been others.
Keep at it....we are enjoying your build!

Hi Jim, thanks for the info.
I believe the Bud Hare bike is under the rider name:
Jeff Gough - 750cc 169.331mph 8/23/1969
The bike was a Partial Streamline class, APS-A
You're right 1 mile is very short and my bike was still pulling hard at the end like nuts, I couldn't even stay wot because of the bumps. My exit speed was 172+
Picture is taken right after my top speed run on the return road.

No Bonneville this year, but I entered a photo competition with a picture I took in 2013 at the AMA event.
There were more than 200 entries and my picture won.
This bike is also my M class bike that holds the El Mirage 650cc APS-VG without a fairing and the A-PF records.

That would make a good "poster child" for why we are not racing this year.

Lots of sweet and sour in that photo! but it's a very good one.
Thanks Alp. :cheers:

Next week is the SCTA October EM meet, I was wondering how fast I have to go to be the fastest 650 naturally aspirated open class bike, not just in the vintage or pushrod classes also in the unlimited class (ohc). As far as I know 179+ is the magic number?
-
Here is something nobody has seen on a sit-on 650 pushrod engine motorcycle.
Naturally aspirated open class with no fairing,,
https://youtu.be/Ioh3hwPcY5c
Yes, it is faster than the 650/750cc pushrod engine special const partial streamline classes.
Enjoy!

Way to go, Alp! Lucky for you I only have one cylinder!

Alp,
You and your Triumph engine land speed bike are all wrong!
The motor's undersquare bore to stroke is antiquated
The stroke is too long for sustained high RPM
The hemi head combustion chamber has too much surface area
The camshaft lift can't be enlarged because the cam will hit the tappet guides
The rocker arm ratio can't be altered because the pushrods will hit the pushrod tubes
Even if you could improve valve lift, the exhaust valve would hit the intake valve at overlap
The 2 bearing crankshaft is too weak
Your carburetors are dinosaurs
Your exhaust is too long
Your intakes are too short
Your bike is too high
You are too big for it! You look like a gazelle on a bicycle!

LOL!!! Maybe that's where we screwed up. Instead of trying to do everything right we should do it wrong and go waaaaaay fast.
-
Here is a list of pushrod engine bikes, I'm not sure what the ECTA numbers are, anybody who knows can add those. But my antiquated engine is in there too. Unfortunately without a fairing at this point.
(http://i66.tinypic.com/35iov21.jpg)
I heard that the ECTA does not measure/seal the motor so we can run in multiple displacement classes,, If Bonneville does not happen and if I can find a sponsor I may come to Loring which I heard is nice.

No kidding, that looks amazing. I love the cradle/brace for the engine. I wonder what that does for modulus of the crank case. Sure can't hurt!

Good choice wobblywalrus, the R/D dept. at Kibblewhite is great.
Here is my new configuration for the Vintage 650cc class, I finished the 1950 Iron cyl. head for this weekend's race at El Mirage. OEM original pre unit crankcases, original 4 fin 6T iron head, 1-3/8 Amal GP's, original Triumph high comp pistons, oem crankshaft and iron barrels.

Nice hole, Alp. I'm looking forward to seeing you at the BMST. I need some advice on using fuel instead of gas to keep up with you!
I'll be running at Loring in July, but no big changes. I may go naked - - open bike class to try to best your "soft" record. I might bring along a 350 Bridgestone for giggles and laughs.

Check with Freud about running naked. It may show your shortcomings.
