About 30 years ago when I got my first road bike, a KZ440, the owner's manual advised to drain the tank prior to long term storage, pour some motor oil in and roll the tank around as much as you can until all surfaces have been coated. At that time I lived in an area where year 'round riding wasn't possible, and that was the method I used. Never had a problem with rust. In fact, I have the original tank off my '07 up in the barn right now using the same method. Of course, the fuel pump is out. I've got no concern about it.
