I have had similar clutch problems.

I have bled the system, I have fitted a replacement slave cylinder, I have replaced the bush in the centre of the clutch (something that apparently gets clogged up and makes you loose feeling in the clutch), I have re-bled the system and everything was fine setting off this morning. Neutral easy to find. Bite point was more than a fingers depth away from the grip. No problems.

By the time I got to the City it was back to its old self. Couldnt get into neutral and had to pull the lever almost back to the grip for bite.
I have no visible signs of leakage - Anyone any ideas please?

For those interested the problem turned out to be one too many spacing plates in the outer edge of the basket. Two on the inside and two on the outside. It should only be one.

I had two on the outside which meant that when cold I could just find neutral, when the plates heated up, clutch became stiffer as it was dragging and no chance of finding neutral.

Out with one plate, neutral easy to find, no longer sounding like a bag of nails, sounds like a Ducati!!

One happy customer.
