Trying to find someone who might have seen something like this before. My son's DS90X destroyed the belt twice when riding in the dunes with 1" oversized tires. After the belt is destroyed when looking at the clutch the belt material is melted to the inside half of the sheave only. The outside halves look new like it never touched that area.
I checked the temperature with a heat gun around the primary assembly and found nothing out of the normal. Just trying to find some reason only the inside half of the sheave would melt the belt but leave no indication of belt failure on the outside half of the sheave. Also the primary sheave is aluminum and secondary is steel. I could really use some ideas!
