250-500cc clutch creep

noticed the 300s creeping a bit when stationary & in gear with clutch lever pulled in with finger or two(doesn't do it if lever pulled right into bar with all fingers but cant ride like that-have shorty 2 finger lever). have the magura hydro clutch on it so no adjustment other than lever position. over 200 hours old so guess plates/steels buggered? change oil every 3 rides or so(250-300km). hope baskets ok?! thoughts all? old girls still goin strong though-so much hill climbing torque & wheel lifting power!

I think the clutch basket has dents on it and the plates of the clutch dont separate well.
