Default Re: Leaky gas cap?

Back in the 1970s I used to use a "Slopper Stopper" on my dirt bikes. Basically it was just a big foam rubber donut that stretched over the gas cap. It still let the tank vent, but when gas dribbled past the cap the foam would soak it up.

Get some open cell foam and cut it in a circle a couple of inches bigger than your gas cap. Then cut a hole in the middle just about the size of the filler neck. Screw on your gas cap, stretch it over the cap and you're good to go!
