Just my weird sense of humor again. I think you're right though, I read on another site that you should keep the gas tank as full as possible to keep exposed areas of the tank to a minimum. Parts that are supposed to be in gasoline should be kept in gasoline as long as it's stabilized to minimize drying out seals, etc. My bike sat in my garage for 20+ years with a half tank of gas, no sta-bil and had no issues with rust in the tank, gum in the carbs, etc. I must have really dodged a bullet and can only guess it may have had to do with the gas being pre-ethanol and just dumb luck.
