And I've never turned the gas off. It makes me believe there is something in the tank when gas sits for a long time and you can never get it all out and its too small for filters to catch, but big enough to hold the float valve open.

Or there could be some gas buildup/tarnish in the hinge of the floats that makes them hang sometimes and not others.

For example, scroll down in this link until you see the floats.
Performance Carburetors - JET Performance Products, Import & Domestic Performance, Performance Kits, Fuel Systems, Transmissions

Since you said this happens on bikes that have sat a while, I would pull the floats out and clean the hinge. I still think its just hanging.

I do know that I had to adjust my floats just slightly out of spec to keep the overflow from leaking. It was out of spec in the direction as if the float was heavier than it should be.
