Sometimes, epo, the float valve will STICK in the OPEN position, allowing fuel to flow freely into the float bowl to the point of overflow.
This condition can be rectified, sometimes, by a SHARP BLOW on the carburetor. The impact frees the float valve hinge mechanism, and allows the float valve to stop the flow of fuel, and to meter the fuel thereafter to the correct float level.
Technique: With bike upright, place a "transfer bar" (i.e., piece of wood, screwdriver, large bolt, etc.) in contact with the top of the carb casting at some point. STRIKE the transfer bar, sharply, but not with sufficient force to disintegrate the casting. Try this several times, and observe whether the unwanted flow of fuel has stopped.
If lucky, you may loosen the float valve, which should function properly . . . until, perhaps, the NEXT time you drop you bike!
I would personally try this trick first, before I embarked upon a "carbectomy" with exploratory surgery, and customized modification of the carb.
