clutch question

[Wasta]

I've recently noticed that the clutch is getting a bit grabby and the changes feel clunky, also the thrust plate no longer stops spinning when the lever is pulled in.

I'm thinking I may need new plates...

If so, where sells them? I've done an internet search and most sites for a '98 M900 seem to be in the US and start at around £280.

I have read on here the stack wants to be no more than 38mm but as of yet I've not had time to remove anything and do some measuring. I will probably need a Ducati tool anyway, which I have not bought or made yet.

Any info would be appreciated.
