Bought as a crusty non-runner, but always wanted to tinker with a 2-speed. Got it running and after reaching its unimpressive maximum potential in stock form, put an A35 top end on it with stock A3 piston (boost ports added) and needle bearing in small con rod end, supporting pipe and carb/intake. Moderately ported intake and fairly aggressively ported exhaust, Polini reeds, Dakar 15.15 and MLM intake. Clutches tuned slightly, pickup still sucks but it rips in 2nd. 42 mph on GPS.
