Hi, Can someone please give me a part# or link for the Variator dampening ring?

I can't find it in the parts schematic.

Thank you.

It *is* shown in the parts list - but unrecognisably! Described as "oil seal x9 125 evolution", it's shown in the wrong position, and not to scale. T-1-08, item 6.


Apparently no harm is done if it's left off...

I have a high pitched whine coming from the left side on acceleration. It stops when I back off the throttle. Above 50, it either stops or I can't hear it over the engine noise.

Through searching the forum I've found some possible causes: Intake air leak, dampening ring, bearing on belt pulley or low gear oil.

Gear oil is fresh and at the bottom mark of the dipstick. I looked over every inch of the intake and see no cracks, holes or problems.

Scooter has new Piaggio belt and Dr. Pulley sliders. I also replace the clutch bearing in the CVT cover.

I'll pull the variator and replace the ring and belt pulley bearing since these parts are cheap enough.

The sound is pretty annoying.
