No. My bike was a bit poorly on Sunday. All sorted now.

My clutch has just started playing up (999 2004). The lever action is perfect until I have cause to hold the clutch in for fairly long periods ie. 1st gear in heavey traffic. Then the clutch 'biting point' gets progressively nearer the bar until finally the clutch drags and prevents me from selecting neutral!
At this stage if the lever is released and pulled back a few times the clutch behaves normally again. I haven't noticed any oil leaks but admit I haven't removed the slave cylinder.
So, do these symptoms mean the master cylinder neads bleading (and is this just a temporary cure) or that the slave cyl needs replacing or both or something else.
Thanks

Sounds like trapped air which is expanding when the temperature is rising thus giving you the above as described. The heat transfer from the engine is greater in traffic with no cooler air flowing over the slave cyclinder. More importantly why is their air in the system, bleed it and if this happens again check for air ingress best starting point is the slave cyclinder itself.

Why does the problem go away (in traffic), straight after a couple or so pumps of the clutch lever when the bike is just as hot?

I have removed the slave. The clutch push rod and in the bore of the slave are wet with blackish oil, everywhere else is bone dry. Is this normal or has the slave seal just started to leak? :(

Clutch help, anyone????

Bike has been into dealers and they have fitted a new slave, bled the system and tested the bike. I went to pick it up and I still have the same problem :mad:

The mechanic wasn't told the symptoms by the guy that booked the bike in! The mechanic says that only a leak can occur from the slave and not a pressure drop. The pressure drop has to come from the master cylinder end. I don't understand this statement. Anyway they are changing the master cylinder tomorrow - I hope that sorts it as I am off to the Alps next Friday!

master cylinder deffinately,

All is well again. Changing the master cylinder finally fixed it.
