What causes ATV to backfire?
Backfiring occurs when one (or more) spark plug in the ATV engine ignites the fuel when it’s out of turn in the chamber, and the exhaust valve on the cylinder is open. In other words, ATV backfiring occurs due to a short, sudden instance when the engine is too lean or too rich.
Why does a 4 stroke engine backfire?
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.
Why does my ATV keep backfiring at idle?
Take note that most ATVs source fresh air at the junction of mufflers and header pipes. If there’s a leak along the system, the engine will keep backfiring. In some instances, a popping exhaust system indicates that the engine has an extremely lean idle circuit.

What causes popping and hesitating on Polaris Pro riders?
That kind of popping/backfiring. You know how if it’s advanced too far it starts real hard and rough but will rev to the moon, but if it’s retarded too much, it starts super fine but sputters and bucks and spits and kicks. Would a sheered woodruff key put off symptoms like this?

What causes the exhaust on an ATV to run hot?
An even more accurate way is to perform a so-called leak-down test. Exhaust leaking before it exits the system will result in a lower back pressure, which may cause the bike to run hot. Look for loose clamps]
Why does my ATV fire at the wrong time?
This means that it’s firing at the wrong time, which is usually because of failing ignition coils, failing high tension leads, or spoilt connectors and switches. When you don’t ride your ATV for a long time, the fuel inside its tank starts to degrade.
