which clutch?

[bluesman]

Just got back after "my regular" 3500 km in France - most of it was hard riding and a lot of playing with clutch when crossing some gravel-covered roads in mountains etc.
By end of ride I got feeling that clutch faded (it is 33000 km on clock now) - not that it's nt working, but it grips much later than before, I actually have to let lever go all way
What would you advice for replacement? I was thinking about getting some aftermarket kit, such like F.C.C. clutch plates and springs...but it is not easy to find.
Anyway - what would you recommend?

Any advice will be appreciated...
