Yesterday I purchased a 2012 800 RMK Pro. 2900 miles. I have heard that around 3000 mile the pistons need replaced. Mostly what I read is he said accounts. On occasion there seems to be verified problems. So what to do what to do. Apparently there is no way to determine the condition of pistons until they let go. It seems to me with the 10's of 1,000's of machines sold there would be more verifiable piston problems. Did a rare event case an avalanche ? How about hearing from riders that have 3000 plus miles with no problems. Thanks for all your help.
