I own a 06 fst switchback and keep burning belts. have had all updates done. 653 miles on my sled and 7 belts. have had clutch alignment checked twice by dealer. have had to replace the foward clutch once because the face got so hot it popped the surface. just sent it back to the dealer for the same problem. belt and clutch burnt. they told me i need to install slp vent kit to fix problem. polaris won't warranty or buy vent kit. anyone else having a problem???? have been riding sleds for a long time and ride with 20 plus other riders. consider my riding normal for a sled. do not drag or snow cross my sled. frustrated!!!!
