GEH (and a few others) have been recommending I bounce up my rear gears. Problem is no one seems to be able to say what gears are already in there (OEM), and i don't want to tear the thing apart just to find out.
So today I put the OEM variator back in (to see if the Dr. Pepper P.O.C. i bought for almost $100 is why I do not see RPMs above 7400). While the cover was off I had an idea.
Marked the clutch bell and the rear tire, then rotated the tire exactly one turn and checked how many revolutions of the bell that corresponded to. Seven and a third clutch revs equals one wheel rev.
Anyone have any idea if that can be used to figure out what gears are in the box?

The good news is that if you are already in the variator, it's just a couple of more bolts to open the gear box. By the way, did your RPMs go back to normal with the OEM variator? I'm guessing they will. |

RE: gearbox: have to take the wheel off and go in from the right side (I think) For that have to take the muffler & exhaust off,. And so on and so on and so on. Only have one gasket. Might be more trouble than it's worth. .... |

Your rpms may still be low due to the heavy weights . |

Count the teeth on these two gears . the smaller one will be pressed into another gear .  |

I don't know about all the different setups, but as I recall, on my 150 gy6, at the rear there are three or four bolts around the back of the variator/clutch area, where you put your gear oil in. You take the cover off and voila, gears.  |

I think he knows where they are , but not what gears are in there.

Actually, I guess I was under the mistaken impression the gearbox cover opened from the WHEEL side, not the variator side. If it opens from the left it's a good deal easier to get to.
How likely is it the gasket remains undamaged?

Well , never mind scoot , I guess it was good u mentioned that . rcq , 50cc's open from the other side , but the 150cc opens from behind the clutch assembly.
