Overflow is the sign of a float stuck or the fuel inlet valve that the float runs is stuck or has a buggar in it. Black smoke is a sign of a rich mixture, which may also be from a stuck float/fuel inlet valve. Still carb problems, there.

Any water in the gas? Remove the water trap bowl at the bottom of the petcock, (gas valve). Any water or trash in the bowl? ( not all bikes have a water trap bowl ). Drain all the old gas from the tank. Install an in-line fuel filter. You will need to clean the built up varnish from the evaporated gas out of the carbs.
FOR EACH carb > Remove the float bowl and clean the entire carb with a spray carb cleaner from the auto parts store. Wear protective goggles to avoid getting spray in your eyes. Spray all the little airways and fittings in the carb. Remove the two screws on the outside throat of the carb and spray into the screw holes as well.

Be sure to put these two screws back in the same hole they came out of. IMPORTANT > do not tighten these two screws down. Only screw these in until they LIGHTLY seat. Now turn each screw one and one half turns outward. Put the rest of the carb back together, clean the air filter and install the carb. Let the float bowl fill then start the engine. Balance and sync the carbs.
I strongly suggest you to let the shop take care of the carbs. Cleaning can be a nightmare times four and doing the balancing and sync of the carbs sounds easier than it is. If you do the carb work then be sure you have a fire extinguisher at hand. I am serious about that.
Please rate this solution. Thanks!
