I _just_ had my clutch m/c on my '86 900 fail. The bolster can stay, but if you have an air distribution duct (black plastic thing), that needs to be moved out of the way to see what you're doing. In the case of mine, the "saddle" wore through & broke off the end of the pushrod going into the m/c. I'm going to drill and tap a thread into the pushrod, screw the saddle back on, and _then_ braze it together (belt & suspenders approach). > If it's the master cylinder, it would likely be leaky seals, though it could > also be the return spring inside the cylinder (I replaced one of these springs > myself a few months back).

If the bore of the cyl is good, you can do the whole job from inside the passenger compartment if you enjoy being upside-down more than you enjoy getting at that one fitting. But, unless you have huge forearms, it's easy enough to go the one extra step and take the fitting out of the front of the m/c. Dave Hinz
