These are some of the root issues that could be causing the fuel/air mixture to be imbalanced in the first place.
Either way, this main reason why your ATV is backfiring can be broken down into a few more reasons that will be shared below. Primarily, you will likely find that the fuel filter is clogged or the carburetor is packed with “old” oil. If you find that not enough fuel is mixed in this ratio, then this could indicate another issue. To function properly, remember that the engine needs to have both the fuel and air at the proper proportion.
In the same sense, the imbalance is what causes the backfiring as the combustion chamber is not filled with the right amount of both “ingredients” simultaneously. In addition to there being too much fuel, you may also find that there are too little fuel and too much air. However, too much fuel could indicate a fuel leak, and too little air could indicate a clogged component of your vehicle such as the air filter, exhaust, or beyond. What this really means is that the equilibrium that is needed to cause the vehicle to work properly is off, and you will likely experience the resulting backfiring. In this sense, you can see that there is “too much fuel” or “too little air”. Then, you will feel the effects of this minor explosion occurring in the wrong location as the sudden pop causes you to startle and your vehicle to jump along with you.Īn imbalanced fuel/air mixture can be viewed from a few different angles that typically cause the same result: a backfiring ATV. When this happens, the excess fuel will become ignited by the spark plug- the igniting will just take place outside of where it is supposed to (the combustion chamber). However, if there is too much fuel (and consequently too little air) being supplied, then it is likely that the excess fuel will leak outside of the chamber. Ignited by the spark plug, the engine is given the power that it needs to propel forward. In order for your ATV to work, a specified balance of fuel and air enter into the combustion chamber. Here’s someone with a Raptor 660 having backfiring issues to give you an idea of what this could look like.

Or, you can always have the vehicle inspected by a professional if you are unsure of what could be causing the problem. When this issue begins to take place more frequently, then you should attempt to narrow down the issue through the process of elimination. Though, that might not be the most comforting thought when you or your loved one feels the sharp jolt caused by the backfiring vehicle.

Continue reading to learn more about common reasons why ATVs backfire and how to fix the issue when it happens. With that in mind, you should take caution, but likely will only need to take action should this become a common occurrence.įortunately, there are many areas that you can check to resolve the issue. Though this might sound (and feel) incredibly intimidating, you should know that it is a relatively common occurrence with ATVs. Common reasons include issues with the fuel/air mixture, carburetor, ignition, or fuel pump. This minor explosion takes place in the engine’s intake or exhaust and can cause the vehicle to shut off. Were you recently driving your ATV and noticed a sudden and loud bang or pop, potentially causing you to jolt forward? It is likely that this was resulting from your ATV backfiring- something that is relatively common but can still be concerning.ĪTVs commonly backfire due to the imbalance of air and fuel sparked outside of the combustion chamber.
