ATV Bogs Down When Giving Gas? What It Means & How To Fix It

atv bogs when giving gas

An all-terrain vehicle or ATV has several names in different countries. Sometimes it is known as a LUV or light utility vehicle, quad bike, or just quad. Even if it has different identifications, there is a common issue that is bogging down, especially when giving gas.

The most common reason when an ATV bogs down when giving gas is a dirty air filter and/or carburetor. This happens when the ATV is continuously used after some time. Fixing these issues is easy – clean the air filter and/or check and adjust the carburetor.

Aside from these reasons, there are also other reasons why an ATV bog down. In this article, we will list all possible causes of an ATV bogging down, especially when giving gas and how to fix these causes.

Why Does an ATV Bog Down, and How to Fix It?

There can be a multitude of reasons why an ATV bog downs. The common reasons are when airflow or fuel is inefficient or when the ignition to the carburetor is insufficient. In these cases, it means that the air filter is dirty, as well as the carburetor. The solutions to these issues are simple and are as follows:

  1. Check and clean the air filter. When the air filter is dirty, that is when there is a “foreign matter” or mixture in the ATV’s air or fuel, this causes the machine to be inefficient in fuel delivery. The bogging down usually disappears once the air filter is cleaned. However, if the problem does not go away, it is best to buy a new air filter to change your existing filter.
  1. Check and clean the carburetor. It is important to check and clean the carburetor from time to time. It is inevitable that the carburetor becomes dirty after several uses. Follow these steps when checking and cleaning the carburetor:
  • First, you need to check the adjustment of the carburetor. Be careful when disassembling the carburetor, especially if it is your first time. You must make sure that you don’t bend the small metal tab by the float assembly because this is your adjustment. Once you are done with the disassembly, you need to check online about the specifications of your float assembly to make appropriate adjustments or buy a Clymer manual and follow its instructions.
  • Second, you need to clean the carburetor by removing the float bowl, then pulling out all the jets. Soak them in a carburetor cleaner, and afterward, blow out with compressed air.
  • Once you have finished the adjustment and the cleaning, put them back together.
  • It is best to have the seafoam run in from time to time to maintain the carburetor’s cleanliness.

The issue of bogging down is usually gone after this. If you are unsure about how to do this, several shops can fix a carburetor at a low cost.

We also can’t exclude driver error, especially when it’s a first-time rider. The remedy for this instance would be consistent practice with the ATV.

What It Means When an ATV Bogs Down When Giving Gas and How to Fix It

As mentioned earlier, an ATV bogs down when airflow or fuel is inefficient or when the ignition to the carburetor is insufficient. Notwithstanding these issues, there are also other causes why an ATV bogs down, most noticeably when giving gas. The ATV starts well, stays strong while idle but suddenly bogs down when giving gas. A dirty air filter or carburetor may be the reason for this, thus requiring the same solutions.

However, those are not the only causes of an ATV bogging down when giving gas. The following issues are also possible causes of bogging down of your ATV when giving gas and the corresponding solutions for these problems.

  1. Old or dirty gas tank. A lot of ATV owners often forget to clean their gas tanks, thus leaving gasoline clot/s in the tank. This clot causes a slow transfer of fuel to the engine or outright prevents the fuel from reaching the engine. To clean the tank, gently remove it and pull the petcock off. Flush it with a garden hose along with a cleaning kit, then use a can of compressed air until it dries. Gently put the tank back and place the petcock. If cleaning is no longer possible, replace the tank.
  2. Dirty Transfer Pump Screen. Check the pressure, then pull out the transfer pump screen, then dip it into a half-full bucket of water. While submerged, examine the transfer pump screen. Then, drain the fuel inside the ATV and refill it. Place the transfer pump screen back and check the difference.
  3. An evaporative Emission System. If your ATV has been with you for a while now, there could be problems with the emission system. This usually happens when the system gets warmer and causes issues such as bogging down when the ATV is in full throttle. At this point, it is best to get your ATV checked by a professional, preferably by an authorized mechanic of the manufacturer, or if unavailable, a mechanic who is familiar with the ATV’s emission system.

A Bit More About ATV’s

The all-terrain vehicle or ATV, LUV, quad bike, or quad is a street-legal vehicle in several countries, but in some states and territories, it is not road-worthy and cannot be used on public roads. This means that ATVs can only be used on private roads or areas.

This vehicle travels on low-pressure tires; its seat is straddled by an operator who uses the handlebars for steering control. The ATV was a popular sports vehicle early in its inception but gained wider popularity during the 1970s when it was used in agriculture and farming as a tractor alternative.

The ATV can be traced back to the 19th century when Royal Enfield, a brand name in Worcestershire, sold motorcycles, bicycles, and sold the first powered quadricycle. It’s designed as a horseless carriage for road use. Then in the 1960s to early 1970s, the term “ATV” was coined but referred to non-straddle-ridden, usually six-wheeled amphibious ATVs.

Also, within this timeframe, the first three-wheeled ATV, which was straddle-ridden with a sit-in style, was introduced. However, the three-wheeled ATV, called ATC or all-terrain cycle, ceased production by 1987 due to safety concerns.

The existing four-wheeler ATVs were first sold in the 1980s. Since then, they are in production and continuously being upgraded to cater to the different needs of its riders. One of its innovations is an age-specific ATV. Most ATV manufacturers are now conscious of the age range of their riders and developed ATVs for a specific age group. If the rider is in their teens, a Youth ATV would be an appropriate ATV since this vehicle is optimized for them.

With its long history and never-ending advancements in its mechanical engineering and modernizations in its usage, an ATV is still susceptible to breaking down. Like any other vehicle or machine, the wear and tear will eventually take its toll.

Final Words

The all-terrain vehicle is a welcome addition to the existing modes of transportation in our human history. Its invention can be traced back to the 19th century, but modern models were introduced to the market in the 1980s. It has several uses, from agricultural and farming to recreational and competitive riding.

Despite the advances in the implemented technology for ATVs, it is not an indestructible vehicle and still faces issues with its functionality after long-term use.

The most common cause of an ATV bog down is a dirty air filter and/or dirty carburetor. These issues also apply to instances of bog down when giving gas. The solution to these issues is cleaning the air filter and carburetor or buying a new one when no longer possible. It is also advisable to use seafoam once in a while to maintain the cleanliness of the carburetor.

It is also possible that the ATV bogs down due to driver error. This is common with first-time riders. With consistent practice over time, driver error will no longer be a cause for ATV bog down.

Aside from these common issues, another set of issues were presented, which may cause bog down when giving gas and their respective solutions to fix these problems. These are (a) dirty gas tank, (b) dirty pump screen, and (c) warm emission system. The solutions were (a) cleaning the gas tank, (b) examining the pump screen, and (c) letting a professional mechanic check the emission system of the ATV.

Newly bought ATV will rarely present these issues. However, if they do, it is best to visit a professional mechanic who can investigate your vehicle and make sure that your safety will not be compromised. Always ride safely and responsibly.
