[QUOTE="Monkeypants, post: 55943, member: 2708"] My Rapide had an oil leak in that area recently. It turned out to be a crack in the valve cap itself. The crack was difficult to see as it was caused by too much force on the cap wrench. All of the flats on the cap had short vertical lines from the use of the wrench over the years and one of those lines had oil weeping from it. I replaced the cap with a spare I had been given, knowing that the problem was solved. It was a bit of a shock to still see oil leaking in the area, but now a reduced amount. It turned out that the replacement cap had a tiny pinhole in it! Here is something else I learned- if you do have a cracked or pinholed cap, do not attempt to weld it. Instead, use JB weld or some other epoxy. The caps are not a weldable alloy, at least the cracked one I destroyed while attempting to weld was not. In doing so I broke the number one rule of motorcycle repair- Do not break the part you are attempting to repair! Glen [/QUOTE]
