I bought a 1980 cx 500 custom early this summer. The bike runs perfectly, as these bikes will run forever if properly taken care of. The only problem i am having with it is a leaky master cylinder. Brake fluid oozes out the gaps in the fluid container when i use the brake just moderately hard, but the harder i squeeze, the more the fluid that comes out. any suggestions on how to fix this besides trying to seal the leak with automotive glue(i have already tried this). thanks.
