I was out for a ride yesterday. Did one long stretch of 1/2 gear rocky stuff. Stopped for a bit and I could hear the gas bubbling in the tank. Shut the bike off, took the gas cap off and steam was coming out, gas was boiling. I couldn't beleive it. When I took the cap off, it made a bit of a swoosh noise, but not too much. My bike is an 07 SE. It ran fine, didn't notice any performance issues. But it looks like the gas cap is moved forward, getting real close to the ignition switch on my TT bar clamps/dashboard. Strangly though, the tank itself didn't feel that hot? I just don't get it. I guess the gas is under some pressure in the tank and has a much lower boiling point then water. My vent tube isn't plugged, the tank area is clean underneath the cover, I don't have any of the three mods so what gives? Maybe I'll try premium next time around. I'm a little concerned about this as this is friggen dangerous. The gas vapors are coming out of the tube and right near the hot exhaust...since we know the exhaust glows red hot...I might be riding a ticking time bomb!
