Thanks for all the responses boys! After reading them and doing a little internet research, I think I may have two problems going on now. The last few days in addition to the shudder, I sometimes get a clunk when I start to accelerate (happens around 5 mph). It's like something all of a sudden lets loose and the scoot jerks forward. It also happens occasionally when I slow down at around 5 mph. A couple weeks ago was the first time I have ever seen the cvt compartment, so I'm a newbie here. The belt looked good, although I didn't check its width. By reading this forum and poking around the internet, I have a pretty good idea how the variator half works, but the clutch side is a different story. Anyway, here is what my gut feeling tells me, the shudder is from flat spots on the rollers and the clunk has something to do with the clutch. I guess to start, I should measure the width of the belt, remove the variator (any way to do this without an impact wrench?) and check out the rollers to verify what size they are and if there are flat spots. Should I take sandpaper to the ramps if they are rough? Should I use loctite when replacing the variator nut? Then we have the clutch......a broken spring would be pretty obvious, but would a rubber cushion out of place or a clutch pad holder sticking be obvious to a rookie? Also, if I take the clutch apart, will there be spring-loaded parts flying all over the place? Guess I'll have to take a look at the parts manual again and see if that helps any. Any other words of wisdom for a rookie about to remove a variator and clutch for the first time? Thanks again for your help!
