Have had that same problem. fill the tank up all the way in cold weather. Get to Tulsa and it is 20 degrees warmer. The bike sits a bit and the sun hits the tank. Smell of gas and looks like it took a piss. No big deal just do not fill it up all the way in really cold weather while riding into warm weather.
Been so bored this weekend and depressed. First week end off in a couple of weeks and the weather sucks. Talking to you all is fun and entertaining thanks.
