    Hello, I am currently building a Trayl Trek 1.0 mountain bike with a 79cc Predator engine 4 stroke. Looking for ideas and trouble shooting recommendations. I will have a few questions soon.

    Welcome to the forum! Watch out for speeding tickets with that setup.

    It does 12mph.
  4. lol a 66 goes more than that i would look into it a bit more because 79 pred should go a lot faster

    they top out at 3500 rpm if I remember right, if it's still got the governor on it and is geared for hills 12 mph sounds about right

    It is maybe 15+, I have governor out internally, I have 11T max torque clutch (2000 rpm engagement), 11T Jackshaft in, 10T Jackshaft out, 44T on wheel. My question is about the Jackshaft in Sprocket. Would a larger sprocket on the Jackshaft In sprocket help me increase speed and power? Just wondering if running a 11T clutch to a 11T sprocket maxes out? I have larger sprocket ordered.
