I have the same bike and same problem. Check the intake hose that connects the carb to the motor it may have a crack mine did and lost power when the bike warmed up. They don't make a replacement hose for it so I am using a rubber plumbers coupling with hose clamps. Might work? The hose is inch and a half diameter and about three inches long try that maybe. Good luck If it makes a chirping sound when the bike gets warm it's probably that hose sucking in air and screwingup your mixture.
