I have a similar project going on now. I am putting a GX200 electric start clone motor into a 1949 3 wheel truck replica. I have bought a comet cvt from BMI Karting. I am running it to a driveshaft, without a jackshaft. On a 2 wheel bike, you will need a jackshaft arrangement of some sort. I saw several of these conversions at the VMBC show this year. Hopefully these pictures will help. I spoke to a guy with one of these conversions and he said he rides this thing all over the place.
