I've got a Sigma slipper clutch which I understand is similar or maybe identical to a Yoyodyne. The clutch stack height is about 2.1mm more than the distance between the pressure plate and the clutch hub, and 1.0 to 1.5 is recommended. It doesn't sound like alot, but it is enough to basically cause the slipper to act like a normal clutch(i.e. a lot of engine braking). I've got a new stock clutch pack for a 1st generation SV(just over 31mm thick). Anyway, how do I decrease the stack height by about 1mm? Does anyone know what a 2nd generation SV clutch stack measures? Thanks in advance!
I know yamaha sells different thickness steel plates that you use to tune the slipper. Check with suzuki to see if they do that or check with aftermarket companies to see if they have different thickness steel plates. Good luck
