Your carb needs to be cleaned. More specifically, the pilot jet, but if it's clogged it'd be best to go ahead and clean the whole thing.
Remove the carb from your bike and then remove the bowl from the bottom. You'll then be looking at the jets and float valve. The jet causing your issue is the smallest one. Remove it and carefully spray it out with carb cleaner. Then hold the jet up and see if you can see light through the hole and that it appears clean and round-meaning no obstruction left. Locate the mixture screw on the outside of the carb. It should use a flat screwdriver. First turn the screw in and count the number of turns. Then remove the screw, followed by the spring and ,if applicable, a small o-ring. Spray through the hole and make sure it goes through and comes out somewhere. Replace the screw in the reverse order and set to the original setting you counted in the beginning.(rough estimate is 1.5 turns out. Cleanliness is the key to the carb working. So keep it spotless inside and reinstall. This should take care of your problem.
