Default Nighthawk 250 wont idle & move

the bike sat for about 2years.
put new battery in it and new gas

the bike wouldn't start, then i messed with the choke and the idle screw and finally got the thing to fire and start. i let it warm up for about 30 mins while adjusting the choke and the idle screw.

it idles ok, but when i give it some gas the bike dies out. i read in the manual that the choke should be all the way down when the bike is idling. the choke is not all the way down and i cant start the bike unless the choke is up a little.

when i put the bike in 1st gear and let go of the clutch, the bike dies out.

any help would be appreciated.

It sounds like the jets/floats/slides(if vacuum operated) in the carb(s?) may be clogged and you have to use a lot of choke to get it to run.

It's just barely getting enough fuel in the engine. Then when you crack the throttle, its not putting more fuel in the cylinders and it's just leaning the bike out from all the air going in.

Get some Gum-out or other carb cleaner, disassemble the carbs clean them well, reinstall and see if the problem persists.

Sometimes the complete opposite is true as well, lots of fuel, not enough air. Cleaning the carbs of all that old fuel will help in either situation.

Also checking the plugs can help to see what kind of a situation you have. Really black can mean rich, copperish-grey leaner. If they are old just get rid of them, they are a variable in a bad running engine you want to be able to eliminate.
