Clutch issues -too hard basket??
In an ongoing clutch saga, I am still having problems with my K1200RS 2002 model 69000 km.
Clutch is slipping; that is, it takes a while for the clutch to engage fully then every thing is fine until I actuate clutch again to change gear and things repeat.
What I’ve done so far.
Pulled clutch out, examined it, perfectly OK - no oil on it, and well within spec.Reinstalled clutch with new oil O ring.
Renewed clutch slave cylinder with new unit.
Renewed clutch master cylinder with a good second hand unit – (seemed to be working perfectly, very smooth and quick action when not attached to clutch line, similar action to another known good unit).
Other issues noted which I think are related
Clutch seems to FEEL at handle to actuate properly (but slow to engage at wheel end) , but after squeezing in and releasing several times, clutch goes ‘hard’ (as you expect in the front brake type of 'hard' when brake pulled on) and you can only pull the clutch in about 20 to 30% of the way. After about 5 seconds, a repeat grasp of the lever allows clutch to be fully pulled into the handle bar. This happened before I renewed slave and master cylinders as well. It is as though the clutch fluid is taking it’s time to release back into the system? The clutch fluid seemed a bit dirty andI tried replacing it – but not have confident I replaced all in that was in the line. Clymer manual suggests among other things, clutch plate spring may be too weak but I find this hard to believe as it seemed fine when I pulled the clutch out. My guess is there is something in the hydraulic line but since there is a new slave and master, it only leaves the line and it seems all too odd to me. Any ideas out there as to what might be going on?
