Hey, got stuck with my VT1100C, clutch diaphragm is dead, not available aftermarket or oem. But found out that VFR400 NC30 have similar diaphragms, can anybody please tell me outside and inside diameters? Even from broken one, need to know if I could swap them, if smaller I have lathe, so no issue here. For VFR I could buy, even aftermarket, but not sure about dimensions...
