Only have 549 miles on my 08' XP 154 and it twisted the crank. Sold my 05' Summit 1000 because it blew up twice. Either situation was rider error. This loyal ski doo owner is thinking about switching to Polaris because ski doo isn't getting it right. Including the 20 some updates (recalls) that the XP had and all the belts eventhough they were warrantied. Just wondering if anyone else has had crank problems with their XP?
