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. The fuel pump could be supplying weak or low pressureĭepending on the cause, there are plentiful solutions to resolve this common occurrence.Īgain, it is important to recognize that this issue (backfiring) is relatively common with ATVs.The fuel to air mixture is too lean or rich.If your ATV is backfiring, you should check a few of the common reasons: This occurs when there is an imbalance in the fuel to air ratio (among other reasons). Backfiring occurs when a minor explosion takes place in the engine’s intake or exhaust as the spark plug ignites the fuel that has escaped the combustion chamber. If you want to look at the mechanics of why your ATV is backfiring, you can understand the general principle that is causing this to occur.

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. The ATC250R remains a popular model for collectors due to its high-performance 2-stroke engines and racing heritage and the 4-stroke “X” ATCs continue to be popular trail machines.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. This led to the creation of the ATC250R, a 2-stroke racing ATC based on the CR250 motocross line in 1981 and 3 more Sport ATCs, using 4-stroke engines. Originally catering to winter activity, campers, hunters and weekend Recreational riders that ATCs were envisioned for, their research showed there was a market for utility-focused machines for commercial and agricultural use, and dedicated sport models intended for leisure and competition use. As the popularity of ATCs exploded in the late seventies, Honda began to diversify their line. In 1970, Honda created the three-wheeled “All Terrain Cycle” market nearly single-handedly with the release of the Honda US90. The machines lacked luggage racks and other utilitarian features, commonplace on most other ATCs or ATVs. Honda Sport ATCs, produced until 1987, were built specifically for performance, and designed for use in racing, or for aggressive trail riding.
