Re: clocked at 38mph today
Revving it that high will blow your top end very quickly. Lower gearing and more torque is better. Try a reed valve intake, the other intakes on the market don't really do much. Reed valves are one of the reasons 2 stroke dirt bikes put out so much power.
some people say that a motorbike defeats the purpose of a bike. i tell them to get a flintstone's car.
