Clutch plates changed but still having problems

[un4givon]

Ok, so I have a 90 ZX10. The clutch was slipping really bad so I replaced the plates. Now that after the bike warms up, is starts slipping again. High revs with no gain. Please can someone tell me what else may be causing this? I hear that maybe air in my line can do it. Also I have no free play in my clutch lever. I bled my lines and I think I got all the air out, but maybe not. Can this be my problem or where else should I start looking? Thanks guys.

did you change the steel plats or just the fiber? A bike that old the steel plates are problaby getting worn out. Also the type of oil you use can cause it.

Or your clutch may not be adjusted properly. Make sure it is adjusted properly at the case before you adjust it at the lever.

Agreed. If the steel plates are worn or warped, the clutch can still slip.
Air in the clutch line is not likely to be a factor.
