Well its time for a new belt on the Apex and I was looking at the Ultimax and XS belts from Carlisle. They claim to run cooler with less slipping. Has anyone got any first hand experience with either of those belts?
I have ran them on my Apex and was not impressed. thy are softer than stock so thy say thy grip better so less slipping on the clutches = lower heat. I did the break in on mine on the groomed trail ( and I never did this with stock belt) and thy didn't last very long so for my money I will stick with the stockers and get twice the miles. There was no noticeable performance gain.
I did not try an XS belt but tried an U3 and it lasted less then 300 miles!
In fact it exploded at WOT, what a mess and it damaged beyond repair the
"wet left foot plate"
Maybe it is just cause the stocker is worn, but I cant get it to the top of the sheaves in the secondary. I put a couple spacers in but is still about 1.5-2 mil below the sheaves. I did hear the 8dn was a little on the short side so maybe that could be part of the problem.
