I
I had a friend a couple days ago crack his piston rings and that got jammed inside the cylinder walls and destroyed the piston. Im not very handy with ski doo but ive known other friends with like 97s or 99 500s that have dropped pistons, busted cranks, etc. I just dont know if these problems are common in these 90s ski doo 500 enignes, but im curious to know what you guys have to say...
