mine went down over a month and a half ago, just got the parts...
2010 S, just out of warranty.. polaris will not give me a reason why they discontinued the 2010 parts and have the "upgraded" kit. I already know why, but I want to hear why polaris mysteriously recognized the problem, comes out with a fix but won't cover the rzrs with the old part numbers that are a ticking time bomb. its only a matter of time before rzr owners 2010 prior to 5-17-2010 manufacture date will have problems. Maybe we should start a posting how many hrs and miles we had when they went down. from the other owners i have read about its been about 35-40 hrs and almost 500 miles before they pop. also usually breaks in AWD and L. Mine did.
