Bogdan, I don't have the numbers you are looking for but maybe RevMaatin does. He changed his clutch plates at my shop a couple of years ago at the end of one of his Great Divide Rides. I seem to recall we measured his new and old plates but I'm sure I didn't keep any notes. I think he kept the old plates as they were still within service limits. According to my factory service manual supplement for 87-95 the friction plate thickness standard is 2.9-3.1 mm and the service limit is 2.75 mm. Steel plate warp standard is less than 0.2 mm and the service limit is 0.3 mm. Clutch spring free length standard is 34.2 mm and the service limit is 33.1 mm. My supplement for up to 2003 is in the shop. If you want me to check it let me know. Now my Clymers for 87-07 is a bit different. It says: Friction plate thickness is 2.80-3.1 mm new and 2.60 mm service limit. Steel warp is 0.0-0.2 mm new and 0.3 mm service limit. Spring Free length depends on the year: 87-95 34.2 mm new and 33.1 mm service limit. 96-on 38.7 mm new and 36.4 mm service limit. Hope this is helpful.

TwinHeadlight Ernie at Dakota Motosports makes a clutch arm mod that reduces the clutch lever effort.

Bogdan, I arrived at Jeff's after the GDR and suspecting a damaged clutch from the mud we encountered during the ride. My riding compatriot, 'the klrbugeater' blew a clutch in the Wyoming Great Basin that required replacement. Having ridden the same conditions, and the clutch did feel different, I called Jeff, he ordered a clutch pack/steel spacers/springs and had them waiting for me when I arrived some 10 days later. When Jeff and I re-clutched ol' 98, the fiber clutch plates were in spec,showed only minimal wear over against the wear tolerance--all plates checked. However, one metal plate was discolored (suggested by the book to replace any discolored steel plate)--but not warped as checked on a granite table/flat service, but the springs were less than spec. Due to the nature of the purchase--special order, I elected to install the new clutch, metal shims, and definitely springs and have complete confidence in the installation and bike's condition. In retrospect, it was overkill--but I ride long distance and remote locations and I considered it cheap insurance and peace of mind. I still have the old plates in a bag; I would not hesitate to use them for another 27K miles. I would replace the one discolored plate and all the springs and would not hesitate to install them on a bike, or anyone elses bike for that matter. As a side note: why I went ahead and ordered the clutch for my own bike. Based on where we both rode, and the condition of John S./klrbugeater's metal plates that were heat treated to a beautiful blue, and clutch plates that smelled like a fire sale, the probability was high that I sustatined clutch damage as well. As it turned out, I needed springs and one plate at a minimum. We got beautiful service from the Kawi dealer in Riverton, WY. THE BEST. They dropped everything else they were doing, overnighted the parts and changed out the clutch on a Saturday afternoon with out overtime charges. simply the best. "We try to help a bike rider get back on the road, even if we have to stay late because most are working people and they don't need to spend their vacation waiting on a bike repair." I wish we had saved a metal disc/spacer. It would have made a wonderful souvenir. revmaaatin.> > Sorry list, > > Looks like Juno and Yahoo didn't want to work together on that last post. > > Here's what I sent. > > Best, > > Jeff > <><><><><><><> > <><><><><><><> > Bogdan, > > I don't have the numbers you are looking for but maybe RevMaatin does. > He changed his clutch plates at my shop a couple of years ago at the end > of one of his Great Divide Rides.

Man, why do KLR riders have a reputation for being cheap? Put down the krupnik and just replace the friction plates and springs already. Sheesh, 71,000 miles.
