Had sled down in CNP over the weekend , not much snow at the cabins we rented, but anyway, the pos only reved to 8000 on the trails. As soon as I would try to play through some trees....blahh...full throttle and barely moving . Seems real muffled, like something is blocking the exhaust. Checked the can for brocken baffles but heard nothing inside once can was off.Need a good mechanic around Calgary to take a look at it. Anybody know one. I don't want to take it to the local dealers because I did not buy it there and would like to get it back in a week or two.
