Sled: 1997 Polaris XC 600 with a P-85 primary clutch.
I recently had my clutch serviced/rebuilt. After I got it back on my sled I noticed that there was about 3/16" of gap between my belt and the face of the inner sheave after I pushed the belt tight to one side. I have three belts, all used a bit but not too bad, and I used the widest one to gauge the gap, so I know a brand new belt will be a little wider, but not that much. Everything I've read says you should have a .020 gap, which is about 1/60 of an inch. MY QUESTION IS, How important is that gap? I haven't been able to really get out and ride it yet but did notice a slight bog or delay after the clutch engaged at around 5100 rpm in my yard. It will be a pain to remove the clutch, drive it back to the repair shop, and complain to get them to re shim it (technically I didn't specify a width to them, I only assumed that it would be set correct). How much performance will I truly gain from the correct belt to sheave face gap? Also, how much width is truly lost between a new belt and a used belt?
All replies and advice are appreciated!
