Pieguy03 - In reading your post I fear I have fallen victim to the same demise of my 2011 500 HO with less than 400 miles on it. I noticed it missing a little and started getting hard to start. Would backfire during the start. Finally would not start and would backfire when I cranked it. Dropped it off at the shop on Friday 7/26. You get any kind of paperwork from Polaris agreeing to provide the parts?
