Clutch Shot or ?

Postby mikelens » Mon Jul 20, 2015 8:58 am



1995 GL1500 SE 103,000 miles.
Coming home yesterday, got stuck in heavy traffic, temps in the 90's. Clutch felt like it wasn't disengaging fully. Bike didn't seem to roll freely with the clutch pulled in. Had to rev the engine higher to get her moving. Engine bogged down & stalled. Restarted, no problem but only revved up, no go. Clutch lever was soft but full of fluid. Once cooled down, engine starts, shift into gear & nothing; engine revs up but no drive in any gear. Did the clutch go south???

You likely have air in your clutch line. When you squeeze the clutch, the air compresses before it starts building pressure in the fluid to operate the clutch, so it's like you're only pulling the clutch lever in part way. The result is that you're constantly slipping the clutch. Sitting in heavy traffic meant you did a LOT of clutch slipping, and it's likely you've worn the clutch beyond spec.

You'll likely need a new clutch, and definitely need to flush/bleed the clutch system. When was the last time the clutch was flushed and bled?

Thanks for the replies. According to the PO, the fluids were all done last year. Last nite I tried bleeding the system. Clutch lever feels the same thru its travel, no change in the firmness. I had the bike up on the center stand; started in neutral, pulled in the clutch, put it in first, released the clutch & wheel rotates. Pulling in the clutch wheel winds down & stops. Putting the bike on the ground, same routine results in no movement when the clutch is released. Time for a clutch I suppose. Ouch! There goes the piggy bank.

Make sure that the return hole in the clutch master cylinder is clear. It doesn't sound like you're experience exactly the same problem, but this has a potentially easy fix that might be worth trying.

I had a problem with my 88 when I had it that the clutch would slip after shifting and under load. Turned out the return hole in the master cylinder was mostly plugged up. (when I let the clutch back out, the fluid wouldn't return to the reservoir/master cylinder very quickly, so it was like I was very, very slowly releasing the clutch. If that hole is very plugged, it could cause a similar problem to what you're experiencing. Once I cleaned it out, my problem was solved. Once you open the lid for the master cylinder, there's a small 'deflector' (about 1/4" in size) that snaps in and deflects the returning fluid towards the right side of the reservoir. Carefully remove this cover/deflector and then use guitar string or similar to poke into that hole and try to clean it out. A more thorough option would be draining all the fluid from the clutch line, removing the master cylinder, cleaning it well - it's easier to clean and see that the hole is clean when the master cylinder is off the bike etc.

A clutch that slips and won't fully engage is commonly a symptom of a blocked return port. A clutch that won't fully disengage and can prevent you from changing gears is commonly a symptom of air in the hydraulic line.

Tried flushing & bleeding the system. No help. Removed the slave cylinder, started her up & dropped her in first; nothing, engine continues to idle normally. Clutch is toast.

UPDATE on: Clutch Shot or ?

Postby mikelens » Wed Aug 05, 2015 11:38 am

Disassembled & found clutch pack covered/full of grit. Had a mechanic look at it & confirmed plates & steels were totally destroyed. There was hardly any friction material left. The grit was confusing but certainly contributed to the demise of the clutches. When I was cleaning up the mess in the bottom of the housing I found the plastic filter dislodged. It is ground down in a circular pattern. Our best guess is the filter rolled under the outer basket which ground it up.
If it wasn't for bad luck, I wouldn't have any.

Glad you found your problem. I trust that your fix is at least easy (on the pocket).
