We are building a backyard/farm beater minibike with a Clinton Panther in it. I already know I will need a jackshaft to get the gearing (numerically) high enough to get around the flat, sandy property. One option is to mount a small sprocket on the engine, use a larger sprocket on the jackshaft to slow the shaft down, and mount a clutch on that shaft. I don't like that idea, because it seems to put a lot of stress on the clutch, since it would be pulling about 6:1, mounted on the jackshaft, where it would have closer to 12 or 18:1, if mounted on the engine. I don't want to build problems into the little bike.
Rear tire 12.5 inch diameter, and I have 72 and 60 tooth #35 sprockets.
If I do choose to mount a clutch on the engine, it is a 5/8 shaft, 2 stroke engine, can someone get me close to an engagement RPM target? 3000 might be too low. I think I saw a 4200 on Max Torque's website.
