13k mile on mine, and although it is noisy it works fine.
I do hold the clutch in at lights, do use the clutch on up changes (smoother for the pillion), almost allways ride it two up, do use lots of engine braking, and generally ride the bike like it is meant to be ridden.
My 996 had a new clutch at 6k and again at 12k, both by the same dealer. Personally I don't think they were needed but if you don't do them when advised you invalidate the warranty
