Yes sounds like carbs need to be stripped and cleaned once that's done and bike ok you better off putting an inline fuel filter on bike stop any debris going in carb again , filters are good for about 1000 miles so worth putting one in

Hi
I would suggest that you have the valve clearances checked.
Also, check that the carb is clean. Pay particular attention to the PILOT JET as this opperates the idle circuit.

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.

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!
