What the Heck Happened?!?

No, it was a lot more than just the sliders. The sliders were just a symptom of the problem.

The sliders were put in at the dealer to replace the stock rollers that were worn out way too early.

The shaft mics out at 23.97mm all around, but is scored pretty badly in one area. There is a bushing (or what's left of one) from the inner pulley, but the ID on that checks out at 26mm. That's a full 1mm of slop on either side.

I had a chance to ride to work this morning and noticed a distinct lack of noise that's been there since the bike was new. Being new to scooting I had just always assumed that it was normal CVT noise. I mean, the bike was new; that must be normal, right? Apparently not so.

I am guessing that because of that slop - and someone can correct me if I'm wrong - There has been an imbalance in the pulley since it was new that has just been getting progressively worse. It feels like a new bike.

The plate bushings failed. This is very common. When you replace your rollers/sliders, you should always replace the plate bushings with bushings of equal or higher quality than the weights you are using.

You should never only replace weights, always replace the bushings and weights at the same time.
