No they haven't. That video was when it was new. It now has well over 2500 miles on it and the primary has never been off and still on stock belt. I plan on pulling it before my next big ride to check them though. I knew about the loose bolt issue before I bought it. Never been able to get the primary off but I'm going to try a new trick this time. I was able to look at them with a borescope and they "looked ok".

If it is a 2016 you need to make sure the recall/service bulletin was done on the clutch. Other than that the noise is normal and you don't notice it with the cover on. I was just overly worried after reading all the stories on RZR Forum. Got read up there for more than you will ever need to know.

It is normal noise. I made this video when the machine was new. Over 3000 miles now and no issues. I did pull primary at about 2000 miles to check the 3 cover bolts behind it that are know to get lose and they were all in place but all fairly loose. I put high temp loctite and reinstalled them.
