Sorry for a rather late reply - I haven't been on the forum for some time. As a former motorcyclist I wouldn't recommend Avgas in a 2 stroke engine. I can well remember suffering from lead fouling, and coasting to the side of the road with a dead engine. This, I would suggest, is preferable to finding a suitable field in a hurry!
I always fly with a full can in the back seat, and can confirm Ghengis the Engineer's findings about handling - my old Flash 2 is particularly tricky when light.
Hope this helps.
