its got like a divot about 1/3 of the way up from the bottom of the sheave, [/b]

When I machine the clutch Angle I resurface the sheaves.

so I can normally remove any grooving in the lower part of the clutch sheaves.

It's very common on the Ute's. KEBC causes it

Well i will be up front about your question...when you pull the cover and set it on a surface plate and take HGT measurement you will see a minimum of .035 already there the pads are contacting the spider pads to the end plate....This is where things go wrong and need measured ...Ive seen as high as .060...I dont like over 0.100 improvement on closing of the primary for general use and gains...so if its got .040 already you only need .030 off each sheave where it it contacts to put you at 0.100 stack hgt...you can relieve the end plate for this amount so it can see it or take material off the bottom side where the spider screws on.. on extreme circumstance do both....when taking off the spider its a delicate balance and the heavy low horse bikes dont like it...light High hp bikes like it ok and make tire speed early on. If too much is took off between the sheaves it creates duration and travel time where effective belt contact happens and is useless on the trails and hills and wont stay within 1/100th on a light tree on cutting it down ...I like a 5.30 on a .500 and a miss cut clutch wont do that no way shape or form and the more you think springing to it helps...pfft might as well piss in a 60mph headwind..hope I helped...jh
