After a ride Sunday I noticed quite a bit of gas fumes coming out of the overflow tube attached to my left passenger peg. It was a hot day out and I rode for a couple hours so the engine was pretty hot, but there wasnt a whole lot of gas in the tank. Actually it was pretty empty at the end of the ride with over 100 miles on the tank. Also a couple weeks ago after a ride it sounded like the gas was boiling in the tanks. The engine never got above 95*C so I dont think it was the coolant. Has anyone else experienced this?

Im worried about too much fumes building up in my garage, or even catching fire while riding. Has anyone heard of a bike catching fire because of the overflow fumes? Im starting to think wrapping the fuel tank around the engine is not such a great idea after all.
