Well, that's cool, but doesn't really help me. Properly working oem is fine for me. I ordered $64.00 worth of cups, seals, springs and new master piston. Time will tell, but I'm sure that my clutch system will be fine.
I've got 35.55 on the piston, 35.68 on the cylinder. The action is very smooth when I slide the (cupless) piston in and out of the cylinder. Feel's ok. If I cant find spec's by the time the part's get here, it's going back together and I'll just runn it and see how it is.
Really wierd that those numbers are this hard to find. Maybe someone could measure a brand new oem?
