ME and my mom and uncle just went to the U.P. for some lake effect snow riding. My mom just bought a brand new 2003 Ski-doo Legend. 6 miles down the trail the sled stops. We figured it had siezed up and we were right. I had to pull it with my 1992 XCR Indy 440 . But went brought it to a dealer in Ironwood and found out the piston had cracked nearly in half and the half got chipped up and thrown throughout the engine. We think the engine went lean but we dont know yet. It didnt ruin her trip too bad though she still got to ride a Summit for the rest of the trip that we borrowed from a friend. What do you think might have happened?
