I have a custom felt vintage iron bolt. modified for 3.0 tires. I bought a 66cc engine on craigslist and bought everything else separately on ebay. I stupidly bought an old style sbp shift kit, and now im experiencing so many problems that ive lost hope of finishing it and now just want it done! More info: I have: delarto sha clone Multi piece shift kit laser cut, front rim brakes, no rear brakes, no exhaust, home made chain tensioner, I made a chain tensioner but its not great. with it the chain is decent but wont stay on the bike more than 20 rotations and without it it wont stay on it more than 5. i don't even care if it shifts right now i just want it to ride. I could just mount the gear on the left side and go but id need to buy new rear mounts and a new 415 chain. Im so close i just need help.
