Check petrol quality. Check oil level. If found to be reducing on use visit the nearest Authorised Service Station since it could be due to piston and bore problem.,

White smoke from exhaust after changing fuilds

Is it condensation or actual smoke? White smoke is associated with diesel mixed in petrol and with quite strong smells. I suspect that it is condensation as water vapor is a by product of combustion and the motor/exhaust will have to warm up to clear it. Check for water droplets at the end of the exhaust to confirm condensation. Burning oil will cause a blueish smoke to emit from exhausts.

Smoke from exuest

Exhaust smoke from an air-cooled engine will either be oil or excess fuel. On an Innova it will be oil as the engine will not run with a fuel mixture rich enough to show unburned fuel in the exhaust
Oil smoke is generally caused by worn piston rings or worn exhaust valve guides.
Worn piston rings will show smoke all the time the engine is running. Worn valve guides will generate a puff of smoke after the throttle is re-opened after it has been held open for a while and then shut off.

The only cure is to replace the worn components and that may include a new piston/cylinder assembly as on these bikes, a re-bore is more expensive than replacement.

In both cases the engine wear is because the engine oil used failed to deal with the heat of the piston rings and/or valve guides, The usual reason is that the engine was used hard, the oil wasn't of good enough quality to deal with the heat, and broke down around the engine's hottest parts.

If you are going to abuse any small engine, use a (non car brand specific) fully synthetic oil like Amsoil 0w-40, Mobil 1 0w-40 or similar.

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.

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.

Sparks and burning from exhaust, no control over speed.

You have a unique problem caused by excessive oil and carbon build up. The sparks are from excessive oil burning, as is the smoke, and not being able to shut the engine down or contol it is called pre-ignition. There is so much carbon built up inside the combustion chamber it is acting like a glow plug when it gets red hot.

Beyond that I can't say how or why you are getting the excessive carbon build up, other than from the oil.

Double check the oil level. Maybe somehow the engine is being over filled?
