Clutch slave cylinder id

[wraith]

One on the lh is 34mm position

One on the rh 38mm position

I think the lh one is bandit? 

Not a idea what the rh one is possible gsxr slabside?

Any ideas

Could be here’s a pic of my 750 slabby one for comparison 

[wraith]

That looks like the bigger one 

Thanks mate.

No worries

Interesting: I did not know that the piston diameter varies among the slave cylinders for different models. Changing slaves could then help produce a clutch with a lighter pull/greater movement of the pushrod depending on the intended application

Just because my brain is not working  witch one would give the greater movement etc?

Keeping the same master cylinder: smaller slave = more movement at the lever for the same movement at the slave, with a lighter action; larger slave = less movement at the lever for the same movement at the slave and with a a firmer action. Same trade-off as with brakes re: the relative sizes of master cylinders when keeping the same calipers.

Handy info for lever firmness preferability 

mans applications

At least I know what seal kit to order  cheers all great info

Would the different sizes have anything to do with the different clutch springs, coil/diaphragm ? 

[wraith]

Good point, the gsxr slingshot bandit and gsx1100f (as fair as I know) all have 34mm ones and the gsxf are spring not diaphragm.

Yes, this is true: fitting a smaller diameter slave makes the clutch action at the lever lighter but more prone to drag.

What is needed is to know the OEM diameters of clutch master cylinders/slave cylinders for each model, and to then see if the size ratio is associated with spring or diaphram clutch
