If your clutch does this on a regular basis then I would say you need a new clutch. I had the same problem with my 06 600 HO.The problem started after only 150 miles The bushing on the end of the clutch was defective. After 3 attempts back to the dealer Polaris gave me a new clutch under warranty. There is no service buletin for this. I would contact your dealer to check the clutch and turn it into Polaris for a warranty issue.
