Thanks for the replys everyone. I think I may try to T off the hose from the cap to bottom of the tank and add a vent tube. Id like to solve this before it gets hot again so I dont get stranded somewhere.

Location added. I checked the tube your talking about, its not kinked but it is attached to the to a fitting on the bottom of the tank. So it doesnt vent the tank at all. From what I was told that was so any fluids caught in that ring on top of the tank could drain through that line and out of the bottom of the bike. I was told that the gas cap is supposed to vent, anybody know if this is true?

I have a 96 Sport 1100. When it gets hot out or my bike is in the sun the tank pressurizes and forces fuel out through the carbs. It pours out pretty good. If I wiggle the gas cap it releases out a lot of pressure. Any ideas as to why? And how to fix this?
