Whats up with the 2011 motors? The 2012 sleds are coming out and my 2011 motor just got put on back order again till sept. 9. I blew two motors on my sled last year. Both motors had the same problem, Broken cylinder skirts. Now I read they have a new part # for the 2012 cylinder. My dealer said that I will be getting a 2011 motor, not a 2012. I'd like to know from Polaris if there is problem with 2011 cylinder skirts. I guess they need to finish making the 2012s first and then go back and make the 2011. I don't get it. I snowed checked a 2012 with a 4 year warranty . I love the sled, I hope Polaris gets my 2011 and 2012 right this time.
