Ill say it again:
Get the Bentley SC Repair Manual.
Adjust the clutch as per manual.
If the problem persists, most likely disk is at its lifes end.
Post a picture of the underside showing the clutch levers.
The positioning lever can indicate if the disk is worn.
Lots of miles on the clutch?
While you're under there, eyeball the mounts.
