    I bought a Schwinn Cruiser with 80cc kit built on it, was running great until the rear sprocket chain fell off, thus popping my rear tire. I put a whole new tire and rim on it transferring the sprocket over. After finally getting the tensioner right and everything fixed the bike will start ride about a foot then stall ride a couple inches more and then stop very hard leaving tire marks from the rear. Why does she keep dying like this?

    You realize you have to pedal to about a running speed then release the clutch?
    Or your carb needs to be idled up

    So pedal to about 10mph, let the clutch out keep pedaling until the motor kicks in then use the throttle. When you stop you have to pedal to get back up to speed then you can let the clutch out and continue riding, Sounds complicated but once you get the grasp of it, its real easy. If you don't like having to pedal everytime you stop at lights or something you can install a jackshaft kit or sickbikeparts shift kit. Sick bike parts have a very high reputation for their shifter kit so i would recommend them. I bought a cheap jackshaft kit and it was hell to put together. The bike frame was just about had it by the time i was done.... lol :rolleyes:.

    Here are a few things to check.

    1. You need to double check the tension and alignment of your drive sprocket to rear sprocket; especially for new sprockets it needs to be almost perfect (look down from the rear sprocket towards the drive sprocket both chains should be aligned) and you should have about 1/2 to 1" of play in chain
    2. When the engine is engaged, because it might not be 100% tight and mounted to the bike the engine is shifting and causing alignment issues
    3. The chain is getting bundled up in the drive sprocket housing either due to alignment issues or the teeth are not shaped correctly yet

    Also i forgot to mention there is a clicking noise when im rolling, im assuming something isnt lined up right. Very frustrating indeed.

    once the chain stretches and the sprocket teeth gets shaped it should not be a problem. but until then just make sure its perfectly aligned and take it easy on the speed.

    clicking noise can be a broken piston ring. when it catches a port it stops the piston and stops your rear tire.

    Could be a spoke. "..when I'm rolling" suggests that it happens when the engine is not turning over.

    clicking noise in my experience is most likely the chain split link when it goes into the engine housing roll it back and forth and check idf the click is at same point in relation to chain position
