82 GPZ 1100 Clutch Issues was created by pjluckai

Hey guys, long time onlooker, first time poster.

After about a year of looking, I finally found an 82 GPZ 1100 in good condition with a reasonable price tag. So I drove 700km and picked her up. During the first ride I noticed significant clutch slippage (next to no power on revs). The previous owner had proclaimed that he had just had the clutch shimmed, but evidently that is not the case.

So, I took the clutch apart and checked plate thickness; all bang on spec. I went ahead with the degreaser and scotch brite trick to see if residue buildup, etc on the plates was the issue. Topped up with Kawasaki S4 synthetic, and a filter I took it for a spin..... no improvement. Fiddled with the clutch lever adjustment, and nothing either. Are there any other adjustments I'm missing? Owner's manual is in the mail....

Any suggestions for next steps? I'm assuming springs are next on the list....

Thanks

Pete

Check if the clutch plates are correctly fitted, the outside fibre plate might be in the wrong slot (not 100% sure this can be done). The previous owner might not have fitted it correctly and obviously there is some adjustment in the lever.

Do not ride with the slip

First Permanent ride the Z1R since Dec1977 (220,000km) as of June 2015
Second permanent bike 1989 FJ1200 dyno'd 140RWH, great bike.
Third ride is now the Frankenstein 1981 GPZ1100B1, 1983 fully recon motor fitted LOVE THIS BIKE
Forth my work bike FJ1200 1989 (same type as FJ above)

Clutch shimmed, weak springs.

The final friction plate has a certain orientation?

Be sure there are no notches in the aluminum hub. The last one is a friction plate. The outside pressure plate shouldn't have a ridge on it or cracks.

Success! such an easy fix... previous owner had the pushrod adjusted the wrong direction. Oh well, runs like a charm, thanks!

Pretty common malady here, and always a good thing to check first. Glad it was an easy fix!
