Hi all, as you can tell im new to the motorcycle world in a way. I've been learning basic mechanics with fairly good success but my latest issue is with my newly acquired '83 suzuki gsx 250, which is missing the front brake master cylinder on the handle bar, along with the brake lever. I have rung around to suzuki dealers and wreckers in Melbourne and I've now learned that it IS necessary to operate the front caliper, and that I cant just throw any old master cylinder on, because It has to have the right 'bore'. I've also learned that a new or used one will cost anywhere from $150 to $300!!! So Im assuming the 'bore' in this case is the width of the tube sending fluid to the caliper or something? Has anyone had experience with this or know if I can use, say, a Bandit's part to install on my bike?
