Oil Coming Out Of Exhaust On Motorcycle
One of the most common problems that motorcycle riders face is oil coming out of the exhaust. This can be a frustrating issue to deal with, as it can cause damage to your bike and create a mess on the road. In this article, we will explore the reasons why oil comes out of motorcycle exhausts, how to diagnose the problem, and what steps you can take to fix it.
Reasons for Oil Coming Out of Exhaust on Motorcycle
The first step in fixing the problem of oil coming out of the exhaust is to understand what causes it. There are several reasons why oil may be coming out of your motorcycle's exhaust:
- Worn Piston Rings: As the piston rings wear out, oil can leak into the combustion chamber and mix with the fuel. This can cause smoke and oil to come out of the exhaust.
- Worn Valve Guides: The valve guides help to control the flow of oil through the engine. If they become worn, oil can leak into the combustion chamber and cause smoke and oil to come out of the exhaust.
- Overfilled Oil: If you overfill your motorcycle with oil, it can cause the oil to be forced out of the exhaust. This can cause smoke and oil to come out of the exhaust.
- Failed Head Gasket: If the head gasket fails, oil can leak into the combustion chamber and cause smoke and oil to come out of the exhaust.
- Cracked Cylinder Wall: If the cylinder wall is cracked, oil can leak into the combustion chamber and cause smoke and oil to come out of the exhaust.
