Vibration from clutch handle

Post by cabinover »



Thanks for having me folks, new GL1500 owner. Just got this old girl back on her feet after a 5 year vacation. First test today in the yard and something I've never seen before. Pull clutch, shift into 1st, but if I pull the clutch all the way to the handlebar I get a vibration. This vibration feels like the throwout bearing is hitting the springs in the clutch. Back off 1/4" and it goes away.

This vibration is there in every gear except neutral. Anyone seen this before? Thanks


Always learning, still stupid though :lol:

It's a hydraulic clutch so the lever is isolated from the engine, maybe you're feeling some vibration by the lever making contact with the handlebars? I don't know, all I know is I hate trying to chase down vibrations and the like.

Never before...but I suppose it's possible that the slave cylinder is pushing the rod too far into the clutch.
Here's what I'd do..
Get to the clutch bleeder valve..Crack it open just a little..Squeeze the clutch lever bout half way and hold.. Secure the bleeder then release the lever..Start the bike and see if it does the same thing.
I'm thinking that IF the clutch master cylinder return port is plugged,the slave piston will not return to it's normal retracted rest position and progressively push the rod further into the clutch.
It's a easy test..and no cost.

One other possibility...5 years setting..Only seems to do this in gear..
I wonder if there's a "stiction" spot on a clutch plate that's grabbing..Or one of the plates is warped.

I would think you would feel a warped plate when you release the clutch and the plates and linings would start to get compressed.

Not sure what it is but for now it seems to have gone away after a 25 mile first run. Will keep an eye on it and see what happens. Hard to believe the slave cylinder could be set up to push any further than Honda intended it but that certainly feels like what was happening. Thanks for all the thoughts folks. On to other little issues it has like the headlight switch that decided to go dark after switching to low beam tonight. Glad I know the road! Always an adventure with an old bike.

Just a follow up, still no problems with that weird vibration at the end of the clutch handle throw. Must have had gremlins in there that got exorcised with a high speed test run. :lol:

Good to hear.Little rust worms got wiped away.
Wings don't like just setting around.They get grumpy.
