I would just as soon everybody keep your problems to yourself untill you find out what the real problem is.
You just know someone that read the first post is out spreading the word about how a clutch exploded and shredded a drive belt on a brand new RZR. Then telling everyone what a piece of junk the RZR is. I don't want people thinking I bought a piece of junk even if it turns out that way. Its going to hurt the resale value[
I sure don't see a shredded belt, I see a belt that chunked about 4" of the outer skin and would still work to get you home.
I have have not seen one of these clutches but I would guess they would have some kind of adjustment to take up slack on a used belt. You said the dealer thought a bolt backed out. I think the bolt may be the adjusting bolt and when it back out and caused the clutch to tighten up on the belt. Probably during this time with the belt getting tight you stopped and caused the belt to over heat inside clutch pulley and when you took off and got the RPM up the belt threw the rubber off where it over heated. The clutch getting tight would also be why you didn't feel a shift and it felt like it was in gear all the time.
If that is the case thats a very minor problem and didn't rate the blew up my clutch news.
But who knows with the loud pop you heard something did break in the clutch assembly. I hope not.
I really don't know if a clutch adjustment bolt even exists, but it should.
Thats my story and I am sticking to it.[
Good luck and I hope its something simple.
