Strip the carbs!
Fuel coming out of the overflows points to dirty float bowls. Maybe fuel that has turned to goo or varnish over the course of the year!
Worst case scenario is that the bike actually starts, but one (or more) of the small jets is blocked and you ride off and seize it!
Stripping and cleaning the carbs will only take an hour or so if it's your first time, and the problem will probably be immediately apparent as soon as the float bowls are off.
