Gas cap

Post by T-Rat » Thu Nov 12, 2015 5:57 am



My bike, 83 GL1100, seems to have too much vacuum in the fuel tank after a ride. If I open the fuel cap at idle after the engine has run for a while the engine seems to actually idle smother and the idle speed increases slightly and there is a noticeable whoosh sound from the tank. I went to Honda to get a new cap because I figured the vent in the cap isn't working correctly. The cap is no longer available from Honda (thanks Honda). Does anyone know of a good aftermarket cap?

There is a vent in the cap that gets plugged. Soak it in Seafoam or some other solvent and blow it out. Very common complaint and easily remedied.

I soaked my gas cap in white vinegar overnight. Blew it out let it dry completely. Works great.
