Does anyone KNOW or have MEASURED the master cylinder diameter? I see that the OEM P/N fits over 100 Kaw bikes and ATV's, but after searching the 'net for over a week I cannot find the actual dimension from the suppliers. I NEED to know because I like the pre-1991 style body/handles but it will be used on a non-VN750 and I need to calculate the master cylinder to caliper piston ratio to make certain it is a viable option. Yes, I could rip down my bike's cylinder, but then I'd have to spend extra $$'s on the rebuild kit and I'm too frikkin cheap to spend the extra $$'s. Thanks!
