this is my first build and spent a slow 2 1/2 months working on it. building mounts, truing the tires, ect. i am about 90% done. just got the chain on ( no fuel in it yet) and i have no free pedal. its a 80cc raw motor. at some point i have also broken my throttle. minor set back before i ever get to ride the bike. i've been reading this forum for a solution and can't seem to find one. i'm fairly mechanical but this is my first motor so i don't want to mess up by going in blind. any suggestions?
