It is definitely coming out of the hose that connects to the left front fitting on the tank. I removed the hose, turned the fitting, and put the hose back on just to see what affect it would have. Still pissing gas when the bike is sitting in the sun. I know the tank isn't over filled - it's just over half full.
Does the gas cap have a check valve to relieve pressure? Maybe that is sticking.
This is driving me nuts!
