ok so i have taken the carb off i cleaned it out. which there was nothing to clean out.. i made sure all the holes were not clogged. i changed the spark plug and looked at the magneto. everything is good in those areas.. just to recap the motor will run. and when the engine is cold it actully works well. after 2 minutes it starts bogging down if i gas it it boggs down. if i bearly throttle it it runs like 10 miles an hour.. this bike is my transportation to work so i really need to figure this out.. someone please help
