White smoke! If your bike is water cooled it's not good. Check your oil. Just look at the dipstick after a short ride. Is the oil foamy looking? If so water from your cooling system is making its way into the crankcase. Unfortunately this is major.

SOURCE: white smoke coming from exhaust

White smoke could indicate coolant in the combustion chamber. Not likely if you have an air-cooled bike. It could also mean that you are running in a cold climate, if the temp is around 20 or less I would call this normal.

If your bike is water cooled I would keep a close eye on your coolant level and oil level. A blown head gasket could allow water to get into the combustion chamber (causing the smoke) or mix with the oil (even worse). If you notice it using coolant I would have it checked out by a mechanic. If you want to check it yourself, do a compression check on both cylinders. If one is rather low, there is your problem.

SOURCE: white smoke

Are you sure the smoke is white? White smoke is usually caused by antifreeze burning.(This could be a head gasket)

If the smoke is actually light gray it is oil burning.(This would be rings or valve seals)

If it smokes mostly on startup and then stops when it warms up (It could be a worn valve guide or deteriorated valve guide seal (or possibly several) allowing a tiny amount of oil into one or more cylinders).

If it smokes mostly when you are cornering (It could be too much oil in the crankcase).

SOURCE: exhaust pipe comes out white smoke when start bike on side stand

Continuous or just for the 5-10 seconds.
If continuous you may have oil seeping past your pistons oil rings or valve guides oil seals.
Check your spark plug see if they are fouled badly (covered heavily and oily) or just covered by oil and sooth lightly.
If 5-10 sec it is normal as the engine is heating up there are normally a little oil seeping past the seals.

My car has white smoke coming from the exhaust


he causes of white exhaust smoke can vary; however, it is common to see white exhaust smoke when first starting a car, especially on cooler days. This is generally steam caused by condensation. As the engine warms up and the condensation dissipates the white exhaust smoke (steam) is no longer seen. If excessive white exhaust smoke is present well after the engine warms up, it is necessary to have the car inspected for possible internal coolant leaks. Indicators of an internal coolant leak include billowing white exhaust smoke accompanied by a sweet odor or a low coolant reservoir level. An internal coolant leak can also contaminate the engine oil giving it a frothy, milky appearance. Even small amounts of coolant entering the combustion chamber will produce white exhaust smoke.
One of the main causes of white exhaust smoke and coolant loss is a cracked or warped cylinder head, a cracked engine block, or head gasket failure caused by overheating. A cracked head may allow coolant to leak into one or more cylinders or into the combustion chamber of the engine. Dirty coolant, a poorly maintained cooling system, a low coolant level, or a non-functioning cooling fan can cause engine overheating. In addition, engine wear can eventually cause the gaskets to lose their capacity to seal properly allowing internal coolant loss. Intake manifold gasket and head gasket failures are two of the most common sources of internal coolant loss caused by engine wear.
Never remove the radiator cap or coolant reservoir cap while the engine is hot or running as it can cause serious injury; always allow the car to cool down completely first. Checking for a low coolant level in the reservoir is the first step in determining if coolant loss is causing the white exhaust smoke. If the coolant reservoir is at the proper level but excessive white exhaust smoke is present, a cooling system pressure check is required to determine where, if any, coolant leaks are located.

My Ford Windstorm Has White Smoke Coming Out Of Exhaust,ConstanLy,Thick White smoke


White smoke is an indication of water in the exhaust. This can be from condensation in the muffler, but that type of smoke usually dissipates after a minute or two of running. Constant, thick white smoke is usually a sign of water leakage into the combustion chamber(s), either via a blown head gasket, cracked head, or cracked block.

Will only stay running on revs over 2000rpm if I take foot of peddle it cuts out also white smoke from exhaust


What is year--make--model?
Are you losing coolant? The white smoke may be coolant in the combustion cylinder, possibly caused by a head gasket problem. If head gasket problem, fix that first.

With idle issues, clean/check anything that has to do with idle air system. Any applicable trouble codes?

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.

If your not overheating or losing coolant, its more than likely engine oil burning. If it is coolant related, possible blown head gasket.

White smoke coming out of the exhaust when starting the engine?


Its the problem of oil.The oil is getting burned out. The vehicle is either burning oil or it is moisture in the gas chamber if you notice white smoke from the exhaust. This is a common possibility.but in some cases this white smoke is not due to oil burning.In that case   White smoke from the exhaust is a symptom of coolant entering the combustion chamber. Normally this is a sign of a blown head gasket or cracked head. And  this is not a common problem must be repaired immediately. You must STOP driving this vehicle or you will cause serious engine damage. you will have to get both this possibilities checked.
Thanks. you can rate this solution and show your appreciation.
