I am taking a clutch apart for the first time on my 98 700 sx. It was starting to hang up on take off. I pulled the primary off and removed the cover. Surface of cover bushing is rough and so is the shaft it rides on. How much play is ok? Parts or on back order from Yamaha and I am leaving tomorrow for the north woods. Where the belt rides is rough and needs sanded. There is less that I would guess .005 clearance in the bushings. Clutch is stock and not altered with 6000 miles on it. All i need it to do is work for this week end and I am done for the year. I am going to Clutch it after the season any way. Any suggestions? Rollers are all fine, no slop there either and I dont see any flat spots on the weight ramps either. I have seen talk of installing Polaris P85 primary's. Does this line up without moving engine?

anyone?
from the sounds of it you should be throwing that primary in the dishwasher to get rid of all the belt dust in it. did you try getting the bushing from one of the site sponsors? port yamaha is awsome to deal with as is ulmer racing and ritch motor sports. with it all cleaned you should be ok for 1 weekend of use. i would then call allen ulmer or look for a clutching set-up in the tec pages. clutching is the best thing you can do to your sled. i would stay with the yamaha primary. i just saw an empty primary for sale on this site that would work on your sled.

I just got done scuffing the sheaves and polishing the shafts. I will order a kit after this trip. I found a spare in the classifieds I am going to try and pick up on my way there. I dont have a dish washer but I cleaned it with detergent and hot water. What a difference. I guess I will try it tomorrow.

Put 100 miles on it today. Worked great and picked up 3 mph on the lake for a total of 88.5. I guess I should clean this once a year?
