I think i might have made a bad decesion. I just bought my frist sled, which is a 2004 ski-doo summit hmk 800 151, with 900 miles on it, which I am happy with . But now all of my friends and local shops tell me they have to many problems. They are telling me i need to rebuild the motor at 1500 miles is what they are telling me right. I am not sure if anyone can help I would apprecate it. And how much does it cost to rebuild a motor.
