I have a 1978 CX500 and am looking for a rebuild kit for my master cylinder for the front brake. I have found tons of places online and ebay that sell for later models but I am having a tough time finding one for my year. It is the one that is round and metal. Or does anyone know a good place to buy a cheap aftermarket master cylinder that would work on my bike. I like the look of the ones where the reservoir is white plastic and not attached to the lever. Thanks guys.
