Not sure if I have a problem or not, but last night I was riding on some tight / technical trails (steep & off camber also) low range and my belt starts a high pitch chirping noise and I get a lot of driveline chatter unless I was laying into the throttle. Is the belt too tight or too lose or what? Some of the areas on my trails require going slow and being very easy on the throttle, so I cant always be stabbin the throttle to keep it from happening. BTW it is an '08 and has around 30 hours and 90 miles on it.

Have you checked deflection? Sounds like you need to remove the thin shim from your secondary to tighten the belt back into specs. Measure the width of that belt before putting everything back together, by the time my first one got that bad, it was out of width specs or just barely in, so I went ahead and replaced it.

I also do mainly steep, winding, tight rocky riding like you describe. Be careful going really fast in L or H range either one with a loose belt, or it could fail and leave you needing a tow.
