SOURCE: fuel drain tube...i think
Hi,
The fuel overflow is a normal reaction when you run out of fuel. The float partially got stuck in the open position allowing the fuel to fill the bowl . Being stuck, the float will not push on the closing valve to cutoff the supply, hence the overflow. A temporary workaround is to jar the float by tapping solidly on the bottom of the carb bowl where the drain screw is housed. This idea is to jar the floats to move up and close the valves.
In some instances, it is possible that dirt/sand/debris might have past trough the filtering system and block/clog or prevent the closing of the flow valve even if the floats are operating normally. These dirt/sand/debris would have been sitting peacefully at the bottom of the tank but has been agitated and made to flow with the last few fuel left.
of course, the correct action would be to dis-assemble and perform checking/cleaning of the carbs and its associated components/parts.
Just a start, do postback how things turned up or should you need additional information. Good luck and Thank you for using FixYa.

Sounds like it may be drawing air around the intake somewhere. Let it idle and spray around carefully with wd-40 until it speeds up. This will reveal the leak.

1) Make sure your fuel petcock is closed, then detach the gas line coming off it (left underside of tank)
2) Remove the back seat (single acorn nut on rear fender)
3) Remove the front seat (two allen bolts at the back of seat)
4) There are two metric 12mm bolts under the front seat that hold the tank down. Remove them. The tank should be sitting loose on bike, but connected by some wires
5) Disconnect the white wiring harness under the bike. Tank is now totally free to remove.
6) Pull tank up and back at the same time, it will slide off the two rubber mounts at the front.
