My '87 1100 recently developed a leak just below the banjo fitting on the left side. At first it was just a slight wetting, now every pair of pants I wear needs the left knee degreased before I wash them. Ironically, a friend's '87 1100 has a leak in exactly the same location. Is this a common problem? Can the leak be repaired? I was thinking silver solder or maybe some high temp epoxy or ??? Anyone with experience have any suggestions?
