Clutch binding

Just noticed an intermittent problem, as I pull the clutch lever it seems to bind sometimes, almost like the slave piston is catching on bore. This binding only occurs only on the beginning of the lever pull. Once with the engine stopped a squeal sounded with the clutch action but never did it again.


From memory something like this has been posted before, anybody know the fix?

Very smooth after the first 1/2 inch of pull.

Have you pulled the slave cylinder off and looked in there? Itís real easy to check. Then pull the push rod out also and inspect it to see if itís scratched from rubbing on something.

Checked the push rod, it's fine.
Phone the dealer (600 miles away) they said they are aware of the problem then phone me back to say they had been in contact with a Kawasaki Manager and there are only recalls for the 2018 on not my VIN. New replacement slave PN is 99999-0610. They told me to take it into the local dealer (20 miles away) to have them evaluate the problem under warranty. Just a pain in the butt, it's the slave piston tipping over and binding when it gets warmed by the engine. Three bolts to put the better one on and the bike will probably be in the shop for weeks!

"Very smooth after the first 1/2 inch of pull".Well,I musta looked at the wrong vid then.The one I saw was cracking and 'binding' all the way to the grip.

Yep, just gets worse if you don't deal to the problem. Just because it's Brembo doesn't make it perfect. There are a lot of very angry H2 owners due to dealers trying to fix the wrong thing!


The cylinder expands and the piston pushes against a ball bearing to the rod, the piston tips over and binds with the cylinder. The Kawasaki fix I understand is to put another seal close to the end of the piston which fixes leaking problems but the seal actually would provide a bearing surface to stop the binding.

Well, after giving it some more thought I removed the slave cylinder and put a very light smear of Molly grease on the barrel so as not to touch the seal but enough to lube the piston against the cylinder. Went for a ride for a couple of hours and the problem has gone, clutch smooth as.


The problem seems to be a design fault where the recess of the rod in the piston in relation to the seal position causes excess pressure of the piston on the cylinder by tipping it over against the cylinder wall. When the engine heats up the cylinder gets bigger and the piston can tilt more. Proper fix would be to machine an 'O' ring grove in the piston and use the 'O' ring as a bearing.

Glad that was a simple fix.Anything in the manual about that pushrod/piston greasing thing?(I'll look later).

So if this is about something not fitting correctly,i.e. the piston,how does a small amount of grease stop it from doing that?That grease will melt down to nothing (figuratively)pretty quick.Hope it remains okay.Good to know about that.Thanks.
