This picture is the magneto rotor. Poor picture, but can you see how the slot is chewed away? This is what I thought the problem was, but still not sure.  |

Well Jon, the variator is on the crank so when you rotate it back and forth your going to be moving gears attached to it like the sarting mechanism, so I think it would have some play and make some clacking noises. That groove in the flywheel looks pretty brutal, so you're saying now you don't think it's that? I bet it is. Rich

I took it apart to put in a new key in and some other parts. Maybe the play is normal then? I just wasn't sure. Figured I'd ask before I put it back together. I didn't think there should be that slack in there. Right now, I don't know for sure what this noise is. I'll know more later. Ahh, the drama of the Chinese scooter....Sorry this is so long. Thanks! |

Don't be sorry at all, we've all learned from it. The next time somebody brings a problem like this up, boom, we got it! Yes, I think that play and noise is normal, I assume your spark plug is out so there's no stress on the connecting rod and those bearings while you're turning back and forth, so it's the attached internal gears. I'd button it up and crank it up! Of course, if you hear a horrendous grinding noise, there's always the kill switch...........ha. Then you can start a new thread! Hopefully that won't happen. Rich

Just a question for my own curiosity, has anyone ever seen the timing chain stretch out far enough to where the tensioner can't take out all the slack of the chain? I was just picturing in my mind the way a bicycle chain is when you don't have the rear tire back far enough.

I was just picturing in my mind the way a bicycle chain is when you don't have the rear tire back far enough. I've owned several high mileage motorcycles where the chain was worn/stretched that far. Im sure its possible on a scoot. -Zug |

I think it was a loose nut in the gears. I won't say for sure, but it seems it is fixed. I'll get some miles on it before I say it is solved. I don't know what this gear is, but there is a nut that tightens up to some bearings on the crank shaft. I got it tight, put it back together and the noise went away only to come loose again. Tightened it real good a second time with some lock-tite and so far so good. These gears are behind a cover opposite of the CVT. The nut is the one with slots in it, and the gear rides on bearings.  I think your referring to this:
