Got to park the beat for a year at least due to moving away for a year. Any tips before I park it?

Should I drain the tank, or fill it full? (Is there an easy way to drain the tank anyhow?) Is the tank plastic or steel?

What about a few shots of fogging oil. Will this wreck the fuel injection? Will I have to replace the plugs when i fire it back up later on?

Let me know what you guys suggest. I will be parked in heated garage, so that is good.

Thanksl
