Belt/sheave wear question
Hey guys, I've got a '07 660, with about 85hrs and a touch over 900miles on it. I noticed recently that my top speed now has dropped from 41mph when it was new, to about 38-39mph now (bouncing off the rev limiter).
I took the belt and sheave apart to check it out, and I'm seeing some minor wear in the sheave surface (maybe 1/32 in.) in spots. The belt looks to be in good shape.
Is the sheave wear anything to be concerned about? And is there a spec to measure to tell if the belt is worn?
The drive is all stock, no modified sheaves or duner's kits.
