    Engine won't turn over.

    I've recently purchased a 66cc motor from the internet and installed it on my bicycle. It ran great for about 15 minutes before refusing to turn. It seems to be the front drive sprocket (the smaller one) that just will not budge no matter what I do. Considering sending the engine back for a...

    How many miles does an engine of these specs have left?

    How long did your china girl last? How many miles did your 66/80cc 2 stroke engine last? Where did you buy it from. How many miles did it go before you had to replace a part? What was the part?

    Kickstarting a China girl

    http://youtu.be/ZF2eAiXBOrw I can kick start my bike now! Got a new 36 tooth sprocket, removed my broken shifter and put my regular bike chain on the lowest gear. No more annoying petal starts! On a side note, clean your chains. All the goop is from both my chains.
