I have been removing my tank A LOT lately, as I am in the process of jetting and re-jetting, and jetting again. The last few times I pulled the tank, fuel spilled out of one of the evap lines leading to my CA model tank. This didn't used to happen. I have always been careful not to overfill the tank; in fact, since I have been tuning, I have only been filling it 1/2 way max.... to ease repeated tank removal. My bike also hasn't tipped over in about a year.
Any other ideas how gas could get in there?
The hose I am referring to is the one in blue below:
