ALWAYS have a fire extinguisher at hand when working on carburetors.
Drain the carburetors. There should be a screw on the lower side of each carb float bowl. Remove the screw then replace it after the fuel drains. Remove the water trap bowl at the bottom of the petcock, (gas valve). Is there any water or trash in the bowl? Drain a cup of gas from the tank. Is there any water or trash in the cup? Dump it, clean it and re-mount it, (not all bikes have a water trap bowl). Turn the gas back on and wait a minute for the carbs to fill with gas. If the bike doesn't start and run properly then shut off the gas and remove the carburetors from the engine.
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 into all the little airways and fittings in the carb. Remove the idle screw and the air screw on the outside throat of the carb and spray into the screw holes as well.
< < READ CLOSELY > >
Be sure to put these two screws back in the same hole they came out of. IMPORTANT > do not tighten these two adjusters down. Only screw these in until they LIGHTLY seat. Now turn each adjuster one and one half turns outward. Before putting the slides back in the throat of the carbs, move the clip on the jet needle one notch lower. Put the rest of the carb back together and install the carb. Sync the carbs such that the slides on the carbs move at the same exact instant when the throttle is slowly turned from idle speed. Clean or replace the air filter and install an in-line fuel filter. Let the float bowl fill then start the engine. This process should get you back on the road.
Please rate this solution. Thanks!

If it sat for a year without Sta-bil in the gas it is probably gummed up and you will have to remove the carb and clean the gunk out of the inside of it and check out all the passageways to make sure they are clean and open

check that the carb jets are clean if one is blocked up even just a little the motor wont rev up well also check that you have a good fule flow to carb and the air filter is clean,,
you can check the jets in the carb by giving the bike a little choke then try reving it up if it revs it has a blocked jet in the carb
