| |  Bike Stops when Starting
I do not know why this is happening. When I bring the bike to the right momentum to start the engine, and when I release the cluth the bike skids to a full stop and like some one had stepped on the brake. What could be wrong? Please help. |

Is it locking the rear wheel up in a skid? |

The first time it happened I check the engine sprocket that I thought it was the engine got stuck up. When I dis engage the clutch the sprocket is moving so it was not a case of stuck up engine. Realine all the wheels and chain again and tried it the second time and it locks up again and breaks the chain. I now suspecting the chain links as I have used the wallmart brand. Reading on other thread the wall mart brand is not appropriate to the MB chain. |

The fact that it rolls fine until you pop the clutch, tells me that its probably not the chain or sprockets. The chain has no 'slack' in it, right?
Pull off the cover on the right side & see if there is anything obviously wrong? |

Do this little experiment... pull out the spark plug & see if you can spin the engine around by spinning the rear wheel. (let the clutch lever out of course) |

As for the chain there was no slack. Right now I am buying a new 415 chain. Thanks |

Don't disengage the sprocket!! I want to know if there is anything wrong in the engine... so, spin the wheel to make the engine spin!
The engine should turn over very easy!
ALSO... check in the magnito cover for any possible problems.

I had this happen to me also, your sprockets have to be alligned fairly perfectly. If they aren't, and the chain isn't straight and it's not feeding onto the sprocket straight then it will pop off and the engine sprocket will not turn it and it will break. |
