Ok..140 mph....When you gonna tell me what's inside your engine? All that speed isn't just from a low riding position...I promise not to reveal any secrets

Truckedup. I don't know what's inside Alp's engine but I do know that a good tuck position means less drag and less drag means more speed with the same HP. Here's an old but very relevant video for those of us with small capacity engines.


Congrats Alp. Bonneville better be on alert!!

Yes this is the record holder bike for normally aspirated 650cc on gasoline "A-VG" It is also faster than the same class A-VG 750cc and 1000cc records.

There is no unknown in the engine, the difference (or if you want to call it a secret) is the way we get the air in and out. I do my own head work and I think this is the main factor.
I also believe that you have to make sure your engine is well balanced and the balance factor is according to your frame and your cam power-band. At 7000+ RPM this engine is very smooth. A smooth well balanced engine is key.

.......I've done about 15 dyno pulls and felt the bike was smooth for a Triumph 650 OIF at 7000 plus RPM. Testing it on the road my vision was blurred by vibration through the rock hard seat and bare steel foot pegs.
My rider says vibration isn't as bad as his street Triumph 650 at 6000 rpm.

Just finished the P (Pushrod) class 650cc engine for Bonneville.

I'm going to put this one into my stock Triumph frame and run it in the M-PG class, just to break it in. Eventually it will go into the new A class frame.

Looks extremely well Alp. If looks were records you'd have the trophy already. Good luck with it. My effort is not as pretty but if it works I'll live with the looks.

Alp,you running the 650 in MP at Bonneville? We ran 125.00 at the Ohio mile a month ago with a MP 650 Triumph. It's the fastest or close to the fastest time for a MP 650 Triumph in a "stock" frame in any LSR venue..

Yes,make sure it's a swing arm frame not one of those "lower" seating position rigid frames actually MP rules say the seat and handle bars must be above the rear tire unless originally it was lower...
You and Hoof,go fast!!

My compliments on your engine
i see you have a morris/hunt mag there do the rules not permit electronic ign
or this is your preference for high speed runs?(i am not familiar with rules)

Who has a low sitting position?

The stock frame size/geometry is irrelevant, In the M class you have to sit above the tire level and this is what dictates the final height. Your frame is not higher than mine. I'm just tucking in low (: The swing arm frame has better traction and is more stable at high speed, especially on the dry lakes.

This image was taken when I got the M frame record for the vintage class. I will be using the same set up for the Pushrod class.
My hands are above the tire level and thumbs 10" apart,, This bike passed scrutinizing at AMA and SCTA for the M Frame rules!

EI is totally legal in P class, I just like magnetos.

The bike in the photo looks more like A class,are the foot pegs 6 inches in front of the rear axle?

I believe you are a smaller guy than my rider who is a muscular 6 foot 190 pounds. He just can't get low enough because of his size and the bike itself. I'm 6 foot 165 pound old fuck.. but too chicken shit to ram that thing down a concrete runway at 125. But I have done near 100 on public roads with no helmet...
The other factor is building power into the engine...I'm just a hobbyist... built a number of stock engines but this is my first and only modified Triumph engine. I built with reliability in mind and it's really not too far from stock.

Anyways, tear it up and blow by 125!!!

Hey Tony I like your bike and respect your efforts but please make sure you look at my pictures carefully. All the items you have pointed out are totally wrong. The pegs are 7-1/2" in front of the rear axle! Unfortunately I am bigger than your rider as well.
I think it is hard for you to believe it is a M bike because it is faster than the A bikes.

This is why you should come to Bonneville

Hmmm...Must be the angle of the photo above,but it looked those lines you drew show the bar ends below the top of the rear tire.... I run a T140 frame that is stock except for narrowed seat tubes.The bike is lowered only two inches from stock ride height.The fuel tank is from a 250 Triumph.The bike is street ridden on occasion..Your machime is more refined for LSR that's for sure. I'm kinda new to this lSR and haven't seen all that much,but your speed records are quite impressive....You should travel east to run the one mile in rough concrete..I believe you would really jack up the record and get rid of the several BSA's chasing the record.

We're taking about Bonneville or El Mirage next year...Money and time to make a 5000 mile round trip is a slight problem...

As most of you know SpeedWeek was rained out. Kind of a pisser but no one controls the weather. The good news is World Finals is on and extended to a week (weather permitting) We got to the salt on Friday afternoon but the sidecar never came off the trailer. The plan is to make it back to World Finals.

Bill, body work looks wicked! I will be at the world finals too, but I'm going to the AMA Bonneville Speed Trials next week with the A-PG set-up. I will run the M-PG and A-VG at the world finals.
