Sounds like your carb. may be gummed up. Did you start the bike and let the carb. get stabilized fuel into it when you parked it?

You will have a carby problem. When the choke is one, and different fuel circuit is used. When you turn off the choke, you go back to the idle circuit of the carb is used, when under throttle, main jets kick in. You probably have a blockage in one of these circuits. Strip the carb down, clean with carby cleaner, blow out all air circuits and jets with compressed air, then setup the idle mixture and tick over speed. Always work with fresh fuel, and drain off, discard any fuel older than a couple of months. It goes off, and turns to a gel like substance that blocks up your carby. Hope this has explained your problem. Happy to talk to you more about it. A FixYa vote is a great reward for for my time taken to explain this to you. Cheers

Carbs gummed up. Need a serious cleaning or a full ruubers replacement/rebuild kit. Gas turns to gummy when left stting in the fuel bowls.
Use a couple of cans of Sea Foam.. best stuff in the world.

ALWAYS have a fire extinguisher on hand when working on carburetors.
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 should 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 adjusters down. Only screw these in until they LIGHTLY seat. Now turn each adjuster one and one half turns outward. Before putting the slide back in the throat of the carb, move the clip on the jet needle one notch lower. 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.
Please rate this solution. Thanks!
