land speed record is safe for now. the storm trooper bike doesn't perform as expected. the vibrations are disturbing the carb. still looking for a solution. http://c2.ac-images.myspacecdn.com/images02/109/m_1379f6574879471d88b168ccb15c70fd.jpg
the tires are to thin n hard and a very harsh ride i cant find a road smooth enough.

Hey guys/girls. I finally broke the 40mph barrier today hitting a touch over 40. I have 38x700c tires running a 9 speed deore rear cassette. This is with a skyhawk gt5 66cc, rocksolidengines billet head, SBP shift kit with the 10tooth, SBP expansion chamber, velocity stack and ufo filter, MSD ignition lead and a boost bottle. I am also running a 1.5mm jet believe it or not.
Back in October of 2005, a team from Wagner Racing in Alabama set a new 50cc Altered Gasoline motorcycle record with a modified Cobra competition mini-motocross engine. The average of two runs yielded a new record speed of 69.633 , beating the old record by 5mph.
That's pretty fast for 50cc, but not really astoundingly fast; my '84 Yamaha RX50 will do 60 in stock trim with a light rider. And it's not even close to the unlimited 50cc motorcycle record. That would be 133mph, set in 2007 by the Buddfab Streamliner, breaking a record (121.7 mph) set in 1956 by an NSU team with a supercharged, two-stroke 50cc Wankel that produced 13HP running on fuel.

i got a semi-legitimate 42mph today. i was jamming down a super smooth street with my new 32 tooth sprocket. guy in a car paced me from the light, and kept shouting out how fast i was going. maxed out at 42, supposedly.
i gotta get me a speedometer and a camera.

I had a guy yelling and hand gesturing to me that I was going 45mph once. I was a believer. Then I used my GPS....
How did you manage to rev the engine over ten grand?!?
I'm calling B.S. unless you have a gen-u-ine in flight photo on GPS.
Seriously folks, this thread has got to go too.... go here- http://motorbicycling.com/f13/40mph-speed-secrets-revealed-11141-10.html
