After my own idiotic experience , then draining my tank on the 2000 V11 Sport, it refilled with 5.1 US gallons. This is without clicking and coaxing in any extra as I always end up spilling fuel doing that.
Of course, as Al says, you can't get all of that fuel back out under normal circumstances. In another idiotic circumstance I found that when the bike begins to sputter (miles from a gas station) flicking it side to side apparently sloshes a little more trapped fuel down to the pick-up propelling the the poor,dry beast a little further before sputtering again. This embarassing procedure can be carried on repeatedly and, with luck, some source of fuel will appear on the horizon.
