There are two lines that can have gasoline come out of them, one is the evap canister that comes from a vent in the tank and the other is from the overflow ring around the filler neck.
Raw fuel is typical of splashing gas while filling the bike and it comes from that overflow ring area. It's possible the inner cap seal is not seating properly and fuel sloshes into the ring while riding, but that's not typical.
Overfilling the tank also allows raw gas into the vent tube that leads to the evap canister. Having raw gas come out of that tube would mean the charcoal inside the evap can is saturated and isn't typical either.
Both possibilities are usually the result of overfilling the tank, if that's the case try not filling the bike too full. If the evap can does have alot of gas saturating the charcoal inside, it will take awhile for it to dry up.
Unless there is something wrong, that's my best guess. Hope it takes care of itself and you don't have a problem. Good luck.
