Do new piston rings smoke?

But, as the engine warms up; the pistons and rings expand, and start to seal the cylinder walls. As a result, reducing how much oil is blowing past the rings. Eventually, the piston rings wear to the point that there is constant blow-by. So, the engine smokes all the time.

What causes white smoke from exhaust in bike?

The most common reason behind white smoke is burning coolant in the combustion chamber. The coolant shouldn’t enter the chamber, but this may occur with a crack in the cylinder, or the head gasket is damaged or blown.

What are the signs of bad piston rings?

Here is a list of the most common symptoms for bad piston rings:

• White or gray exhaust smoke.
• Excessive oil consumption.
• Low power for acceleration.
• Overall loss of power or poor performance.

What causes white smoke from the exhaust of a dirt bike?
