ok so i have a ninja super bike.just bought a new 49cc engine,clutch..got it all hooked up and mounted last night..got it cranked..but it spins backwards..any way i can get it going the right way? its a free floating sprocket in the back so it just spins around since its going in reverse pretty much.it needs to go the other way for it to catch and tire to spin.Random i kno..but its general tech
