Next motor I'm doing a build with 43cc 2 stroke with cent clutch from a pole chain saw. It actually sounds really good and quiet looking forward to this build. Brainstorming about the shaft. Not using a tranny going direct belt drive to a rim pulley. I'm attaching the rim pulley in a way I haven't see anyone do(no welding either) & I think is going to kick ass. Just planning out the shaft that will have a 3 in V belt pulley. I've already got the gear ratio down strictly looking at options for the shaft.
The shaft is tapered & hollow(from housing a worm drive for the pole chain saw).
I know some of the HuaSheng 49 cc 4 strokes have a tapered shaft that has something like a 22 tooth timing pulley(not trying to go with a timing belt on this one). Is there a way to get a v belt pulley on this shaft?.
Should I just remove this shaft from the clutch bell & change it to a 1/2 in or 5/8 shaft(actually not hard to do?
Should I find a different bell housing all together?
Different clutch flywheel & bell all together?
I believe it's the same bolt pattern as the popular motors for bikes engines/Robin Subaru/Tanaka/Honda/Mitsubishi
Any thoughts?
Thanks in advance. I really appreciate your guys input.
