89 moto4 250

if the bike's just idling, and i stand beside it, grab the racks, and shake it side to side...the motor dies.

it's been running poorly under normal operation... like acting like it's not getting enough gas.

i went through the carb today... to clean out any crud... didn't reset anything though.

any ideas?

 

Make sure petcock valve is on. Ive done the same thing, Basically it has very little gas in the engine so when you shake it gas stops going into it.

 

check the lines coming and going into the carb sounds like there could be a blockage or the jets in the carb r cloged up there kinda hard to clean u need troch tip cleaners just dont break one inside the jet you'll b buying new jets trust me but n the end it my workout better for u i jetted my grizz and man it really helps

 

have you made sure that the coil power wires and spark plug wire are clean and connected good? it is really worth checking.
