Why does my motorcycle keep making a popping noise?

Why does my motorcycle keep making a popping noise?

When your motorcycle engine is running, a mixture of fuel and air is being ignited in the cylinder. When this unburnt fuel comes in contact with the hot pipes, it ignites and causes that distinct popping noise.

Why does my bike pull harder at high RPM?

If the bike pulls harder at high rpm when cold and less hard when fully warmed up, the main jet is too large. Install a smaller main jet and retest until you find the main jet that pulls the hardest at high rpm when fully warmed up. This must be done first – before moving on to the other tuning ranges.

Why are the spark plugs on my motorcycle not working?

A motorcycle running lean can also quickly wear out the spark plugs. This means the carburetor or fuel injector is not inserting enough gas inside the combustion chamber. The gas that does get inserted burns much hotter because there’s more air than there should be.

What are the symptoms of incorrectly gapped spark plugs?

An engine that hesitates, or stumbles, upon acceleration is often the result of incorrectly gapped spark plugs. If spark plugs are gapped too wide, the ignition spark loses some of its strength as it crosses the spark plug gaps. This can result in engine hesitation.

How to find out why my engine is making popping noises?

1 Check for engine codes that may indicate the problem. 2 Run a good quality fuel injection cleaner. 3 Check your spark plugs. 4 Inspect your spark plug wires. 5 Test your engine compression.

What causes spark plugs to get wet and foul out?

According to AA1Car.com, this occurs when the spark plug fails to fire, or fouls out. This can be caused by a number of variables, such as engine flooding, or excessive moisture build up. Failed vehicle starting attempts eventually lead to wet spark plugs, according to E3 Spark Plugs.
