U gotta check this out
Well I posted about my clutch problem that would not totally release. Today I removed the cover and began inspecting the clutch figuring a replacement was in order. Got out the flat plate and calipers removed all the parts all were within specs thicknesses good not even warped a little. Found a little problem with the inner steel that mates against the judder spring. It wore a groove into the steel.
As I was starting to assemble the clutch using old parts because they were still serviceable some fretting black where the springs reside caught my eye.
I tried the clutch when I first removed the cover and noticed it stuck I thought on one side but I wasn't sure. After finding this it makes sense now So I'm wondering if anyone else has ever found this condition? I've never seen a post that I can remember about it. If you have some miles on your bike and the shifting becomes more difficult it might be a cause. The design seems a little weak to me as the springs are not held concentric in the bore and apparently migrate out over time and vibrate against the clutch plate. New plate isn't too bad only 45 at Ron Ayer my springs are a little weak and I'll replace them also.

Hey.. I too had a clutch lever full return issue on my 07. I think I posted in that thread before. Anyway, I solved my issue. I found the lever was gummed up a little at the pivot hole. There was even some surface rust on the steel collar. I cleaned it up real good and greased it a bit and the lever snaps back like new again. The sad part is I bought a new hub and a master cylinder rebuild kit several months back. Still have those parts ready to go.. but it looks like I jumped the gun a bit. Granted, I have not had a chance to ride the bike since the lever clean/lubing.. winter and all.. but it sure does feel right now. Oh well?
As for the your pics and description, I do not quite understand what you mean? Are you talking about the groves cut in your pressure plate spring holes by the clutch springs? I think that;s pretty normal. Maybe I don't understand? Has your pressure plate been painted with black spray paint?

Yes the grooves from the springs cause the plate to hang when the clutch is diengaged for shifting. The plate moves in relation to the springs so after they get so deep they catch.

them springs get worst when you shim or use spacers and compress them more..posted about this way back when i kept seeing sparkle oil at oil changes .. also check your inner hub where the steels ride in the groove{area where steel meet aluminum).. they wear a spot in the hub and then don't move freely and cause clutch slippage.. you can file it out or just buy a new inner hub..

I had that inner hub problem way back with my 750 turbo with a barnett clutch. I filed it down but that was because I would rev it and dump the clutch for wheelies. No need for that with this bike. They Kaw use pretty cheap compnents for the clutch bare aluminum is marginal plus nothing to hold the springs in place.
