Here's my shelby airflow mutant minarelli race bike.
Broke the frame as a pedaler years ago, and chopped and welded it into various configurations for chinese motors, then finally gave up and modified it to take a 70's moped minarelli V1 engine.
Installed a Polini 80cc cylinder kit on it days before racing it at the Grange Motor Circuit kart track in Victorville two weeks ago.
Hit 50+mph in the straight. It'll go faster, just ran out of room on the track.
Got first place in my class, 4 and under horsepower, even after lowsiding in the final.
