I have two CB's a 1972 CB500 and a 1974 CB550K The 72 sat for too long and is becoming a parts donor for the 74 which I bought as a running bike, but it needs alot of attention.
I can find master cylinder rebuild kits that fit 1975-up CB550, 69-up CB750, and others but not my specific year and models. . Are the master cylinders on those bikes different than mine? Would one of those kits work in my master cylinders?
