Greetings brother (and sister) Gear heads! I recently picked up an older used Island hopper rear mount friction drive kit with a blown Honda 31cc 4 stroke motor. The motors toast, no biggie, the friction drive rollers so worn down its almost useless.(I gave the guy $75 bucks for the box of parts) the carrier plate and mounting hardware is all there. A good Honda 50cc 4 stroke replacement isn't that expensive. My idea is this, converting the friction drive to a chain drive/shift kit combo on a dual suspension bike. I think all i might need is some way to convert the friction roller to a #40 chain gear dive, and of course a shift kit/free wheeling crank set.(we love SPB!) Any ideas? KEEP EM RUNNING! BBB. flg.
