I have an 04 900 efi. Last year sled ran perfect. During off season I changed tracks from a 151 x 2 to a 153 x 2.5 I have been out twice this year and it seems like something is wrong in the clutching area. The first ride a burned up a belt and when I finally smelled I checked the clutches and the primary was super hot. This happened when I was in 2-3 ft of powder.
I put on a new belt but it was only for the trail ride home. It seemed fine on the trail.
Second ride out it seemed like the belt was slipping whenever i got into the powder. The primary did get a little warmer than usual but I was checking it often to prevent losing another belt.
The sled has 1150 miles and motor is stock except I will be putting on an rkt 14.8/1 head. I plan on taking the primary apart to check for wear on the weights. I am thinking I should replace the spring but don't know if I should go with the same one. I mainly ride 8,500 - 10,500 ft.
Any suggestions would be appreciated as I am new to the whole clutching thing. Any ideas on why my primary is getting hot when in the deep stuff?
