[QUOTE="bramfrank, post: 516876, member: 2163"] There are several opssibilities; 1. Clutches can slip if you use an oil with friction modifiers - but you said you run an overly expensive, semi-synthetic intended for bikes, so that isn't likely the case. 2. It is possible that you have some debris between the clutch plates, reducing the contact area. 3. You could have a problem with the hydraulic sender or servo that prevents it from retracting. 4. Perhaps you managed to break a clutch spring or have a bad throw bearing. or, more likely, since you've indicated that the engagement point has gone to the limit; 5. You could be low on fluid or there might be air in the system. 6. You've toasted the plates. Having said that, clutch plate replacement is not major surgery and assuming you haven't glazed the pressure plates, a full set of friction plates (there are a total of 9 plates) costs less than $70 plus a new gasket. Could you have worn out the clutch? Absolutely. But if you've been using the clutch gently and have not spent your life in stop-and-go traffic, the clutch should last a long, long time. [/QUOTE]
