Default Hissing noise

Hi. Took long ride on my 2015 roadking on Saturday in hot weather. When home I noticed a hissing noise coming from the gas cap. When I removed cap it stopped and started again when cap on. No performance problems just hissing noise that lasted several minutes. Definitely air pressure. Is this normal. Never heard before. Thanks.

Gas fumes expanding because of the heat. Perfectly normal.

I was in my backyard yesterday with the dogs. I heard a hissing noise and looked over and there was a snake with it's head up and fanned out like a cobra six feet from two of my dogs.

I nearly soiled my shorts until I realized it was an Eastern Hognose snake. Suffice it to say I'd rather hear hissing from my gas cap.
