Here's the deal. I have never even heard of your bike brand but I have 18 years in bike repair. If you promise not to give me anything less than a "helpful" rating I will tell you how to do the fix based on the assumption that the bike has a standard carb and not a CV carb. The standard carb has a top "cap" that unscrews from the center of the carb body.
.
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 or bottom 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. If the bike doesn't start and run properly then shut off the gas and remove the carburetor from the engine. Now unscrew the top cap and pull the slide out of the throat of the carb. When you re-install the slide, be sure the long notch on the side of the slide lines up with the small pin inside the throat of the 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 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!

with 2 stroke engines there is 3 things that you need petrol air and spark if you have them the bike will run you say you have cleaned the carb have you checked the air box the filter could be blocked restricting the amount of air in also have you checked the spark plug remove it and see if you get a spark place the plug onto the engine so thats its touching some metal and try and strart the bike you should get a nice fat spark if you dont then replace the plug if you do have a look at it is it oily and black if so the the air screw on the carb needs turning 1/2 a turn inwards if its white then 1/2 turn out if it looks ok the check for compression place your finger over the hole in the engine where the plug came out and try and start the bike your finger should be pulled gently into the hole if not then the piston ring has either cracked or snapped and will need replacing
if all this is ok spray some easy start into the air box and kick the bke over it should start if it does then a new carb might be needed

hope this helps

SOURCE: I put premium gas in my 07 sportster. It was hard

Your premium probably had ether or alcohol in it, which acted as a solvent for all the old gas gunk in the tank and lines, and gummed up the carb. You'll likely have to finish flushing the tank and lines, and rebuild the carb to clear the gunk.

Thank the gubmint while you're doing all this extra work.
