You can get rapid wear it you rev the bike a lot at stand still, or with the brake on.

The thing is that i don't either, the flat spots on the new rollers are not bigh enough to feel with fingers, but they are big enough to stop on them if i roll them on a table.

What condition are the rollers in? You don't want any flat spots on them. What could be the reason of rollers wearing fast? The new rollers I put in like a week ago already have some minor flattening on them, I didn't even ride in intensively. Were those roller weights from a "tuning" set of rollers? Tuning rollers have softer plastic. |

After reading this whole thread, i think you should disassemble and inspect the rear pulley. Sounds like the pins may be binding in the slots. From what you described, seems like you may have dual angle pin slots on the rear pulley. The pins may be binding up where the slot transitions to the second angle. ...just a thought.

My jog r has a straight cut for the guide pins.from. 0 to 60kph is seamless acceleration ( and I have dialled it down after an engine blew up ) all I have changed from stock is the three clutch springs,polini hi speed variator
And up jetted a little,the speedo drive on this model is prone to failure and bad readings,if you can service the torque drive and try it if no joy measure your drive belt and post what you get.

Is the stock sliding boss on jog a dual angle one? If yes, then yes, the sliding boss in my scooter is a dual angle one. I actually don't want to take apart the clutch, because I don't have correct tools to hold the clutch to unscrew the main bolt holding it and I don't have a 38mm wrench or a socket to disassemble the clutch assembly.
And if the boss is sticking, how do you fix it to not get stuck?

If the torque drive is worn. You have to replace it. The pins slide up and down a groove. The pins wear the groove wider, causing the pins to stick, and not travel smoothly.
You can make a clutch holding tool out of two pieces of flat bar, a few bolts, and nuts. Or use an oil filter tool.
You can get the 38mm nut off with an adjustable wrench.

Dijux,if you don't,t want to tackle the clutch ? Why not just drop the scoot and your credit card at your local Yamaha dealer I,m sure they have the answer.
I,m out

Not a very quick reply but if you rebuild without trueing the crank that can also cause flat spots?
