Smoking motorcycle: reasons and solutions

Before renovation smoking motorcycle, it is necessary to observe the smoke so that the reasons for its appearance can be determined. Indeed, smoke can be white, gray, blue or black depending on the nature, source and severity of the problem.

Smoke is usually caused by poor fuel quality, but to make an accurate diagnosis and find the right solutions, we suggest you look at the types of smoke one by one.

White smoke: reasons and solutions

This type of smoke is less dangerous than others because it happens that it is not dangerous. However, its diagnosis is necessary to avoid engine overheating. Here are some possible sources of white smoke and possible solutions.

Cylinder head gasket problem

White smoke usually occurs when coolant enters the cylinder. and evaporates there. This leak occurs through the cylinder head gasket, which introduces water or antifreeze into the combustion chamber and causes smoke.

Therefore, to solve this problem, it is necessary to check the plan and valve of the cylinder head gasket and replace the latter to make sure it is tight.

Other Causes of White Smoke

In rare cases, white smoke can appear due to impurities in the fuel. This case is more serious and implies that you need to use a higher quality fuel.

However, be careful not to confuse the problematic white smoke with the motorcycle's reaction when pulling off in cold weather, which is perfectly normal. That is why in winter we have to warm up the engine before leaving.

Therefore, in order to avoid this kind of leakage, it is necessary to check the condition of all engine parts. If wear is found on the cylinder head gaskets, piston rings and cylinder walls, repair or even replacement is required.

Black smoke: causes and solutions

Black or very dark smoke indicates a more serious problem than other types of smoke.... Indeed, this could be due to poor carburetion control as well as other mechanical problems.

Black smoke from carburization

The first reason for its appearance is too fatty fuel. Too rich a mixture of fuel and air leads to poor combustion, which leads to engine overheating and, finally, heavy black smoke. Therefore, the solution is to properly balance the amount of fuel and air in the combustion chamber.

Black smoke from defective parts

You will notice that black smoke can also be caused by nozzle leaks, clogged (or dirty) air filter, worn out sensor ... In this case, it is best to call your mechanic.
