hey i have a trx300ex, and for a while it was workign fine, than when i tried to start it up i would touch the throttle and it would make a bogg sound and die, so i drained the gas, cleaned out the fuel filter, and put new gas in and it still isnt working any clue what could cause it-i can start it up now also, but when i hit the throttle it just dies

 

have u checked the carb....you might have gotten water in it somehow

 

turns out it was flooded, but i was gonna check the carb but ended up it was just flooded and had to adjust the choke a little
