how do i drain my tank?

[rockaduc]

Bike is an s2r 800. I'm loosening what the shop manual says is the drain for the tank, but the tank isn't draining at all. There is probably half a tank of fuel I'd like to get out before winter sets in.
Any thoughts?
It's times like this where I miss carbs.

There is no drain.

If you remove the fuel return line and tip the tank up on the prop you'll get most of it...but not all.

You'd have to remove the pump flange to get it all.

Thank-you.
