I just got a2001 honda 400ex and it will run for a couple of seconds then die. I changed the spark plug but just get the same results. Its almost like the fuel is turned off. Any suggestions

has it been sitting? if so drain the gas and put fresh gas in it.

drain the carb bowl too. it could have water or bad gas in it.

does it have an inline fuel filter? if not try cleaning the stock screen that is in the tank on the petcock.

check out the ignition.

does it have one of those silly parking brakes with a govener on it? if so maybe something is wrong there.
