Question about Gas Gas EC 250 Motorcycles
I have cleaned carbarator put new o rings on head changed the plug was told it was running when parked but who knows
I'm assuming it is carburated. Sounds like the float needle (seal) is not sealing. It will dry out when the bike sits up for a while. You should replace it or soak it in oil until it becomes pliable again.

Remove the water trap bowl at the bottom of the petcock, (gas valve). Any water or trash in the bowl? Drain a cup of gas from the tank. Any water or trash in the cup? Dump it, clean it and re-mount it, ( not all bikes have a water trap bowl ).
Drain the carburetor. There should be a screw on the lower side of the carb float bowl. Remove the screw then replace it after the fuel drains. Turn the gas back on and wait a minute for the carb to fill with gas. Install a new stock NGK spark plug and try to start the engine. If the bike doesn't start and run properly then shut off the gas and remove the carburetor from the engine.
Remove the float bowl and clean the entire carb with a spray carb cleaner from the auto parts store. Wear protective goggles to avoid getting spray in your eyes. Spray into all the little airways and fittings in the carb. Remove the two screws on the outside throat of the carb and spray into the screw holes as well.
< < READ CLOSELY > >
Be sure to put these two screws back in the same hole they came out of. IMPORTANT > do not tighten these two screws down. Only screw these in until they LIGHTLY seat. Now turn each screw one and one half turns outward. Put the rest of the carb back together, clean the air filter and install the carb. Let the float bowl fill then start the engine. Set the idle speed with the idle screw. This process should get you back on the road.
The crank seals could be going bad, but clean the carb first.
Please rate this solution. Thanks asimonton84!

If your plug is dry, then there is no fuel. This can happen for two reasons: No compression - be sure to get a compression tester and ensure that there is enough compression produced by the engine to enable the engine to run. More than likely, though, there is no fuel getting to the engine. When cleaning carburetors, it is important that you use a chemical dip. Spraying carb cleaner through it is not enough. Be sure to disassemble completely: fuel float and its needle and seat, all jets, all emulsion tubes, all air cut off systems and accelerator pumps, all enrichment circuits (choke), vaccum slide and diaphragm, all air jets, and last but not least - the idle air/fuel screw. If this is the first time the carb has been taken apart you have to drill the cap to get to the screw. once everything is apart, soak all metal parts in the Berryman or equivalent chemical dip solution for at least several hours. After, run hot water, as hot as you can stand over all dipped components and blow out with compressed air. reassemble and enjoy.

these type manifolds are made of a metal base and a rubber joint. the rubber is hermetically sealed to the metal part. over time, this seal can go bad causing a leak that is undetectable by the average person. if you say you have replaced carb and sprayed around the boot with a pickup in rpm's, i would replace the boots abd orings! this should solve your leand condition.

Testimonial: "Just visited local Kawasaki dealer and mechanic there said same thing. Ordered o-rings, clamps, and carb connector."
if you are getting gas, it's probably too much. is it flooding the motor. make sure your float level height is okay and that your float needle valve assembly is clean and not sticking. if you have an electronic choke, try disconnecting it. it might be malfunctioning. also a possibility your valves need to be adjusted.
