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 ).

Drain the carburetor. There may be a screw on the lower side of the carb float bowl. Remove the screw then replace it after the fuel drains. Turn the gas back on and wait a minute for the carb to fill with gas. Install a new stock NGK spark plug and try to start the engine. If the bike doesn't start and run properly then shut off the gas and remove the carburetor from the engine.

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 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. This process should get you back on the road.

You are going to want to know if yours is fuel injected or carborated. I am pretty fairly certain it has a carb. So you are going to want to go to your gastank and follow the hose to your carborator. There is probably a spring clamp on the hose so take that off shut off your fuel valve. Now take the hose off and put the hose over something you can put gas in and turn on the fuel shut off valve. If gas comes out freely then its your carb if it doesnt its your shut off valve and quite probably you carb. You will then just need to clean them thoughlly and check them again after you get them back together . if it is the shut off valve check it again first before you rip the carb apart. if its fuel injected which i dont think it is email and i will walk you through that.
