Why is my dirt bike exhaust popping?

What is Backfiring in Your Dirt Bike? A backfire manifests as a banging or popping sound from the exhaust or intake system of your dirt bike. The engine can backfire if there is too much air or fuel. The heat of your bike’s exhaust ignites the fuel and causes incomplete combustion.

The spark inside the chamber may not burn up all the fuel, allowing a little extra gasoline vapor to enter the exhaust, and lead to a backfire. This can be caused by a faulty mass airflow sensor or a clogged engine air filter “choking” the engine and not allowing enough oxygen to flow into it.

Is motorcycle exhaust popping bad?

Exhaust popping occurs when unburnt fuel reacts with hot excessive air in a high flowing exhaust system.
