The thing with two strokes is that they smoke a bit under normal operation, and they smoke like mad if they haven't really been run for a period of time, I would advise you to run it for a while and see if that helps.

You should not need to adjust the mixture settings at all.


Hope this helps

Hi, Anonymous your instrument gauges and lights can alert you to most electrical and engine issues they can not warn you about failed engine gaskets or seals so your engine has to resort to old fashion alert methods of colored "SMOKE SIGNALS" here is a breakdown of their meaning:
1. COLORLESS OR SLIGHTLY BLUE SMOKE on start-up means your air/fuel mixture is at the right composition and everything is well burnt in your combustion chamber.
2. BLUE SMOKE on startup is usually caused by failed valve seals dripping oil into the combustion chamber when the engine is not running.
3. YELLOW OR BROWNISH SMOKE at start-up means your air/fuel mixture is too lean. Too lean means that there is low fuel but high air mixture in your combustion chamber.
4. WHITE SMOKE on startup may be caused by a blown head gasket allowing coolant to enter the combustion chamber and may start dripping out of the exhaust pipes or mufflers. Smoke while riding is usually caused by worn out or damaged valves, seals, guides, pistons, rings, or cylinder walls.
5. BLACK SMOKE on startup is usually caused by too much fuel in the combustion chamber this can be due to air/fuel mixture adjustment too rich, accelerator pump improperly adjusted, faulty choke/enrichner or not in the off position, air filter dirty and clogged, faulty carburetor float needle and seat, pilot jet too large, fuel injectors leaking, smoke while riding is usually caused by the main jet being too large or a damaged carburetor.
It should be noted that aggressive or abnormal throttle operation will cause these conditions to manifest themselves exponentially.

Engine problems on a kx 250 2 stroke


On a 2 stroke bike cause of smoke is due to excess oil in the fuel oil mixture, incomplete combustion in the cylinder or the engine oil finding it way in through the piston rings into the firing chamber. Check the oil levels and clean the plugs, which must be black in color by now, so replace if possible and if engine oil is low, the change the piston rings. Also look up the carburetor jets/nozzles are clean and the engine gets the correct fuel/air mixture by adjusting both fuel and air jets(turns)...sodeep

Hard starting smokes white like gas is getting into cylinders


White smoke in a small engine is oil. Oil in the cylinder will create too much pressure for the engine to achieve compression. Make sure the engine is not getting fuel into the oil and thinning the mixture (literally smell the oil... gasoline and oil smell nothing alike, if it smells like gas, it is). If this is the case, the carb is leaking fuel into the engine, thinning the oil and causing the oil to leak past the rings into the cylinder head, through the valves and, from there, into the exhaust to burn off. Black smoke indicates a direct fuel issue in a small engine, white is oil based.
