Losing Clutch Freeplay

[l2will]

I have a 95 R1100R w/abs and have been losing freeplay.

Before going to Top O the Rockies, I did a full freeplay adjustment by setting the clutch lever adjustment to 10 mm and then adjusting the clutch end to get the recommended 7 mm of freeplay. The lockrings at both ends of the cable were locked
down.

After about 2000 miles, the freeplay was almost gone and the
clutch began to slip. Then the clutch lever end was adjusted to get the 7mm of freeplay back and prvent the slippage I was getting.

The question is, what is going on? Seems to me that if the clutch is wearing out, the amount of freeplay would be increasing, not decreasing.

Any ideas?????

thanks,

Lyle,
As the friction disk wears, the clearance will decrease. The pushrod presses on the center of the spring plate, the spring plate exerts pressure on the friction disk and the driven plate from the front of the clutch pack. Any decrease in thickness will decrease the clearance at the pushrod.

Guess I am concerned about the number of times the freeplay
has gone from 7mm to 1 or 2 mm. Then the clucth starts to slip
noticibly when accelerating.

Prior to the full adjustment, I had adjusted the freeplay at the clutch end only at least three times this summer already.

So from what you are saying, the friction plate is wearing away
very quickly.

So I guess I will need a new clutch soon... right?

How many total miles on the existing clutch? The only other part that I can see causing the same failure is the clutch rod thrust piston (throw out bearing). It is housed at the rear of the transmission and 'can' melt if the temps from a failed bearing get to it. You didn't mention any noise associated with your disappearing clearance so I would assume the disk is wearing, rapidly.

Just 25000 miles on this clutch and on the bike.

I am not hearing any unusual noies, so I think it is the friction
disk.

thanks for the info
