Clutch MC Piston too big

[Constant Mesh]

On my '04 the clutch disengages with just a small movement of the clutch lever. You don't have to pull it back very far to break the connection. Most of the lever's movement occurs after the clutch is disengaged.

My manual transmission car is the opposite. I have to push the pedal almost all the way to the floor to break the connection.

Both have hydraulic clutches.

I wish they had used a smaller diameter piston in the FJR's master cylinder. You'd have to pull it back a bit more to disengage but it would be easier to pull -- the mechanical advantage would be greater.

Maybe the typical rider doesn't want to pull the lever back much -- quicker shifts, etc.

I'd prefer a bigger mechanical advantage with its longer piston stroke.

Swap the slave cylinder with one from a Gen II ( larger diameter ) to

achieve your desired results.

I have one lying around. Interested?

I thought the GenII slave was a smaller diameter which resulted in a harder clutch pull? Am I mis-remembering?

You may be able to bring the clutch lever closer to the grip using the adjustment.

Edit: I think the later Gen II slaves changed but only back to the same as the Gen I. (Although I may be mis-remembering again)

I believe they changed back from 2009 on...............

Doh! At my age my Advanced CRS kicks in all too often.

I got it backwards. The Gen II is indeed the smaller one.

Sorry for the confusion.

Bleed the clutch fluid. Get all the old fluid out of the master cylinder and get fresh stuff in there and throughout the entire system. You may find a difference in feel and engagement.

Nothing wrong with the clutch fluid. Doesn't need bleeding.

It works too well. Only requires a minimal movement of the lever to operate the clutch.

Have you tried different aftermarket levers - there are a few chinese knockoffs that work pretty well, I got some off fleabay that work great, maybe give ya a bit of a different angle / torque !?!?!?

The GenII slave is going to make the effort worse..... I swapped mine out for a GenI slave.... much better, but longer stroke. Pazzo levers recommended which will improve the situation somewhat, but not a quantum leap.
