    Fixes for a leaky gas cap.

    I have a 1983 Yamaha XS400 SECA. I don't ever overfill the tank. But I noticed that when leaning the bike on tighter turns gas would dribble through the tank gas cap and run down the side of my tank. Now, I wasn't surprised by this. It's a 40 year old bike so I can only assume that some of...
