Winterizing and Storage

[Sev]

I would never store an empty, used gas tank inside a house. Even an empty tank is an explosion hazard that can be triggered by a static electrical spark, very common in a heated, low humidity environment.

The OP had mentioned sticking the bike inside his app't. I didn't say it was a good idea, but if you're going to do it, you should drain the tank. Then, you COULD spray some WD40 inside the tank to keep it from rusting, and prevent gasoline explosions.
