White smoke means coolant in the combustion chamber. Most likely a blown head gasket. You will have to tear the engine apart to be sure.

My dirt bike is pushing out smoke when i hit the gas, why is it doing that??


Hi, Candice and the usual suspects are:
1. Oil tank/pan overfilled.
2. Restricted oil return line to oil tank/pan.
3. Restricted breather operation.
4. Restricted oil filter.
5. Piston rings badly worn or broken.
6. Valve guides worn and or seals worn, crushed, missing, or have come of guide and are literally pumping oil through the valve guide.
7. O-ring damaged or missing from oil pump at crankcase junction (also results in poor engine performance). For more information about your issue and valuable "FREE" downloads that you will need please click on the links below. Good luck and have a nice day.

Excess smoke from exhaust


I would make sure the oil level is not too high. Next I would remove a spark plug and test compression to see whether your rings are worn excessively.Hope this helps.

What makes a 2005 Yamaha YZ 450 F Blow Oil Out The Crank Case Hose Into The Breather And White Smoke Out The Pipe Thanks


Hi, Shawn_luke_I oil level readings are taken when the engine has reached normal operating temperature and the usual suspects are:
1. Overfilled oil tank dipstick reading should at or below full.
2. If the sight glass is full you are running to much oil.
3. Excessive blowby caused by worn out piston rings.
4. Piston rings never properly seated.
5. Faulty breather valve or system.
6. Pinched or clogged breather line/hose.
7. Clogged or failed oil filter.
8. Contaminated oil dirt-rust-water etc.
9. Excessive oil foaming.
10. Wrong oil type not designed for your bike.

2002 TDR 125: excessive white smoke from exhaust driving at 65 k...


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. WHITE SMOKE on start-up can is usually caused by a blown head gasket allowing coolant to enter the combustion chamber and may start dripping out of the exhaust pipes or mufflers.
2. BLUE SMOKE on start-up is usually caused by failed valve seals. Smoke that is constant while riding is usually caused by valve to guide and piston ring clearances that have exceeded service wear limits.
3. BLACK SMOKE on start-up 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, 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.
It should be noted that aggressive or abnormal throttle operation will cause these conditions to manifest themselves exponentially.
