Why does my dirt bike exhaust smoke?
Those engines normally emit a blue/gray smoke. But if it’s excessive then you’ve got a burning oil problem, a rich fuel condition like noted above, a bad spark plug or a malfunctioning power valve. Excessive clearance between the valve stem and the valve guide. Worn or damaged piston rings.
Is a 2 stroke dirt bike supposed to smoke?
Since the engine is burning pre-mix oil we have to be careful here, because blueish-white smoke is a normal occurrence of two-stroke engine operation. However, excessive smoke after warm up can be an indicator of a couple problems.
Why does my pit bike smoke so much?
Smoke is either water or oil being burned. Assuming your pitbike is not water cooled then it is oil getting into the combustion chamber. There are a few different reasons why that could be happening…. piston rings are a possible culprit or it can be getting in from around the valves.
What do you do if your dirt bike is smoking?
So if your bike is producing a ton of white smoke, you need to turn it off immediately. This is a tell-tale sign of water getting into the cylinder. The “water” is actually antifreeze that is leaking around a gasket or a crack in the manifold. If you catch it soon enough, it might just be a head gasket that is leaking.
How do I stop my dirt bike from smoking?
Black smoke is generally the result of a rich air fuel mixture. This is more common on a 4 stroke and can be seen if you leave the choke on too long when warming your bike up. Properly jetting the carb or tuning the fuel injection will get rid of any black smoke if everything else is working properly.
What does it mean if my 4 stroke is smoking?
If it is a 4 stroke, it means that oil is getting past your piston rings. This will make it where oil is in the cylinder during combustion, which produces the blue grey smoke. Second, since there is a ring failure, you are not going to have great compression which can cause a multitude of running issues.
What causes smoke coming out of exhaust pipe on dirt bike?
When cylinders go bad, gaskets leak or really anything internal on your dirt bike or ATV engine that allows for flawed combustion of fuel or any fluid used for the proper function of a 2-stroke or 4-stroke the telltale sign is usually seen coming out of the exhaust pipe.
Is it normal to smoke on a dirt bike?
It depends on what type of dirt bike you are riding. If it is a 2 stroke, smoking is normal. If it is a 4 stroke, smoking at start up MAY be normal. One thing to look at is the color of the smoke, as that tells quite a bit about what is going on.
What happens if your motorcycle is smoking a lot?
If your bike is smoking a lot and the smoke is black or very dark, you may have a problem of poor carburetion. In this case, you will notice other symptoms of mechanical failure in your machine, such as the engine bogging down and even stopping while in motion.
Why does my motorcycle exhaust have black soot on it?
Black soot on the spark plugs suggests that the fuel/air mixture is too rich, resulting in gray exhaust smoke. A shiny, wet, black film on the plugs is a result of excess oil, and this causes blue smoke.

Why does my dirt bike have blue smoke in it?
You can see the blue looking smoke in dirt bikes that have unwanted oil mixing with the air-fuel mixture. It means there’s a contaminant with the cylinders and their combustion along with the air and fuel. This cross-contamination is caused by the engine where the cylinders, Pistons and valves along with failed seals.
