I have a gsxr 1100 with a hydraulic clutch.just recently had Barnett plates put in it.Seems fine off the start but at around 8000 to 9000 RPM seems to be slipping,could it be that it needs to be bled?

Did you change the springs when you changed plates? Soak the new plates in the same oil you run in the bike before installing them?

A clutch that needs bleeding will not disengage fully, you seem to have the opposite problem, so I doubt that's the cause.

yes springs were changed also,and I run Motul synthetic oil in it which i just changed to recently.off the start and shifting through gears bike is fine just seems at high RPM when I come onto it the that the tach goes higher but no more pull.Was cold outside the other day but I doubt the back tire was actually breaking loose

About all I can come with is to open it back up and check everything was put back together correctly and that the new plates haven't glazed.

If you had it done by a third party, I'd take it back to them and have them ride it to prove the problem, then let them remedy it.

Did you replace the metal plates as well? If you did then it's possible that they were the wrong thickness. If they aren't thick enough then the clutch will slip.

well thought I would try the bike out again today,went about 5 mile made a stop and it wouldnt move at all with the clutch let out...what a work out pushing 5 miles home,how can a new clutch go south that qiuck???Could it be the synthetic oil....Motul 10 40.Someone told me today to dump it and change the filter and put in regular Suzuki oil...Help help help.With the bike on a stand and put in gear clutch released it wont even turn the back wheel..

If your engine oil has some sort of "friction modifiers" it's possible that it basically caused your clutch to slip until it cooked itself...

Just out of interest, did you adjust the clutch cable fully?

I'd go back to the start, and make sure the clutch is assembled correctly, and that it's the right stack height. Make sure the plates aren't cooked as well.

well I dont know much about this stuff sorry but read the label it says it is okay for wet clutches,but some one told me told not to use synthetic when the clutch is new,I didnt put it in just purchased the bike a few weeks ago.Now I only rode about 10 mile total would that cook the clutch that qiuckly??They guy changed plates springs and put in Barnett discs

Sounds like the clutch assembly was put together incorrectly. Might be missing a friction plate, maybe the factory messed up and shipped the wrong friction plates and/or clutch plates, etc...

You're probably going to have to break into the clutch assembly with a micrometer and make sure everything is present and in spec. If you don't want to do that, you're going to have to bring it to a shop and explain the problem.
