Master cylinder bore size? Good replacements?

[scott-s]

 I can't seem to find this info anywhere.

 

 2000 GSX750F Teapot. What size is the front master cylinder? 

 

 I'll probably have to replace mine and I'm looking at new aftermarket but don't know the size. OR...good used from another bike. What are some good master cylinders from other bikes that will work that I should be on the lookout for?

 

 Stock calipers and rotors, braided lines. EBC pads.

 Is it 5/8" (16mm)? 

 

**EDIT**

 It's 14mm. I dug out the old master cylinder and found the stamp on it. It's actually not in bad shape. I think I may have Bern thinking about the one from the '80 GS550. 

 Still, if you know of a nicer/better/more modern replacement,  I'm all ears. 

 Can you even get a radial master cylinder in 14mm? Would a 16mm radial work? I'm a little confused about the radial....they often mention bore size and ratio. What do they mean by ratio?
