so.... I think that I once heard that gas caps should vent a little so that a suction isn't created as the gas drains into the intake... but my cap is ridiculous, if the tank is full and I go for a ride I will definitely have gas and oil crud leaking out of the cap and running down my tank... Is this common? is there a way to fix it? Should I just buy a new cap?

This is common
The fix is: Don't top your tank off. Fill it till about half an inch under the edge and the problem is solved.
Its probably leaking from the gasket, not the vent anyway. Like what has already been mentioned just don't top the tank all the way off.
I ave some rubber that is perfect for making those gasket seals
Cork works good too
What kind of rubber do you use? Like silicone from a tube, or what?
Cut a few from old truck inner tubes (enough material to make hundreds of gaskets).
Bump for more info...
When you cut out the gasket seal,
do you just cut out a circle kind of, and then glue it to the underside of the cap?
No glue. There are two metal tabs that hold the gas cap to the frame. A rubber circle gasket can be strectched over those tabs and they hold it in place. It is loose, but at least it won't fall off.
Cool, I'll find some kind of rubber that'll work, and try that.
