Long term storage: empty or full?

Tried the search function to no avail.

I’m about to have to store the bike for 6 months. It will be in a well ventilated garage, potential freezing temperatures, on a battery tender, but NOT running at all.

I don’t have the means to REMOVE the tank to go all out on draining, so there still be a LITTLE gas at the bottom. But do I run it until empty before storing? Or just fill the tank?
