The spacing is different on the two motors. Even the head gaskets don't match up. I could probably make it fit without the sleeves on the head bolts but I'm not trying to make a death trap  |

So 60teeth for regular gy6 starter clutch, and 50 teeth for a gy6b? I found a 50 tooth for a regular gy6. Switching starter clutches might be my only hope of having a running scoot...

Not to change topic but is it possible at all to use the jug and head from a regular gy6 on a gy6b? Everything seems to fit good. Would the cam chain be too long? Could I just switch cam chains?

Been awhile since I've been on here, a year and a half to be exact. I have 2 motors. A regular GY6 157qmj and gy6-B with the 16" back wheel. The starter clutch in the GY6 is shot. I already know most of the parts are not interchangeable. But haven't heard anything about the starter clutch. My question is Does anyone know if you can use a starter clutch from a GY6B with the 16" back wheel on a regular GY6 with the 12" back wheel? Im trying to save time and gaskets from tearing both motors apart to find out. And save money on buying a starter clutch if I can use it  Any help is greatly appreciated. Thanks! Daniel |

Can installing a piston upside down scar the port side of the piston? I installed a 70cc kit and put the port on the piston exhaust down. 3 miles later the motor screeched to a stop and pulled it apart and saw that the piston was scarred beyond use only on the port side, it forged the rings flat to the piston.

Where exactly do you measure it when doing this?

My motor just hit 16,000 miles. I changed the reed valves today and the metal stopper I guess you would call it was closer in on these. Is there a factory measurement for these? I'm fresh into the 2T world. But so far I'm loving it! |

I'm running a 100 jet in mine. Exhaust and straight carb. It runs great. But I don't recommend trying it with a stock air box and exhaust. Mine didn't have the air box when I bought it so I bumped the jet size to make up for the extra intake...
