Rode my 2004 rm 250 for 2hrs as soon as i got to the truck it started to bog down and i kept turning the throttle and it didnt work it died? i change spark plug have spark. i cleaned the air filter and re-oiled it and tried starting. It didnt work i kick and kick nothing happens and about every three or four kicks it will back fire anyone have any advice. It will be greatly appreciated.
Sounds like fuel restriction causing lean mixture. Look for debris in carb float bowl and jets .

Install a new NGK spark plug ONE HEAT RANGE HOTTER THAN STOCK . Now go back to the 32/1 gas mix. The 32/1 is what lubricates the crank bearings and piston. At 44/1 you are asking for a seized piston and/or the need for new crank bearings. Be sure to use Two Stroke Engine Oil in the gas, NOT motor oil. Use premium gas, not regular. This should take care of plug fouling.
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 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.
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. This process should get you back on the road.
Please rate this solution as " FixYa " if all goes well. Thanks

If you have air fuel and spark, you have everything it takes UNLESS! That wire did a no no like shorting out. Where did the wire go? and what color was it?.

could be water in the carb, or dirt in the carb also

Pull the fuel hose off to see if fuel will run out when the fuel tap is 'on'. If nothing, check the tap filter screen for plugging and clean it with spray carburetor cleaner. If you get fuel to run out, try checking the float needle in the carburetor for sticking.

water in fuel / in correct mixure/ bad spark plug
