Here is a step by step way to flush your carbs.
Most likely you have trash in the carb needle seats. Take the drain plug out of the bottom of each carb and let the fuel drain out, then use the little red spray tube with a can of Gumout Carburetor Cleaner to load the float bowl with it, holding a finger over the drain plug hole, and spraying up through the drain plug screw hole. Flood the float bowl with the Gumout, then remove the spray tube and your finger. Couple of times with each carb ought to do it. It's easier to tell when the bowl is flooded if you pull the vent hose out of the right ear and let it dangle out the side; Gumout will come out the tube when it's full. Replace the drain plug, put the vent tube back in the right ear and close the drain plugs. Turn the petcock on, fire up the bike, and see how she runs then.
In your case you might want to switch one of the spark plugs from the front cylinder to the rear cylinder, before you fire it up or install another set of plugs.
Then run some Sea Foam in your fuel for a while, the instructions are on the can.
