jet it if you havent. maybe a timing key, ignition, take off the airbox cover. i dont think it takes too much.

turn the idle up, it helps a little, and like the other guys said, jet it, or take the airbox lid off.

You could try tires in some situations if you dont alredy have some. You could also try an air filter or jet kit.
