sounds like my bike a little while ago and a friends at the weekend, in both cases whipped off the pressure plat and the friction plates were almost smooth ... sounds like the it may be the case here, I'd do that before bleeding and rebleeding again ... just to be sure ....

its easy ...

1. Remove clutch cover
2. Undo the six spring bolts and remove bolts and springs.
3. Gently pull pressure plate away and the push rod will come with it ...
4. Pull a few plates out and have a look, ou are only interested in the friction plates ....
5. If plates are ok then put back in same order that you removed them ....
6. If plates are buggered then theres your answer, new clutch plates required, order and install ..

whole excecise takes about 10-15 minutes.
