I have a 09 ski doo 800 reneagade and I took it on its first trip to the UP last week, ran great the first two days and on the third day it ran like it was on one cylinder, checked the plugs, they looked great and had 150 compression in both cylinders, It sounds kind of like a four stroke and runs weak. it also leaked some anti freeze that the dealer said there was a recall on and he would change it when I got home. Anyone else have any similar problems with their machine. Needless to say I wasn't real happy my new sled with 280 miles sat on the trailer my last day!!!!! I was thinking its probably something in the computer, no warning lights came on the dash. Does anyone know Scott at Scotts repair in Christmas??? He looked at it and couldnt figure it out either. He also thought it was the computer. Good Guy! Thanks in advance for any replies.
