Master cylinder found

Q: Last issue, Dennis Ventura wrote in looking for a rear brake master cylinder for his 1983 Kawasaki GPz750. He recently sourced a cheap and effective replacement and wrote in to tell us about it. Well done! — Ed.

A: I wanted to give you an update regarding my GPz rear brake woes. I solved the problem by going to a nearby Japanese bike salvage yard and just plunking down the old one on the table and asking, “What do you have that looks like this?” The gentleman helping me came back with one that looked similar, complete with remote reservoir, from a late-model Kawasaki Ninja 250cc. Everything lined up. I used the 1983 mounting bolts and the line from the master cylinder to the rear caliper was the same size, as well. The reservoir even went into place using the 1983 hardware. It cost $50. I forgot just how much fun that bike is to ride. Dennis Ventura/via email
