Common problems with a quad bike or an ATV

quad bike guide parts

Common problems with quad bikes can occur. I think it is important to remember, that quad bikes are vehicles, just like cars, so they need to be regularly maintained to solve common problems with a quad bike or an ATV.

The most common problems with a quad bike or an ATV are:

  • Issues with the battery
  • Ignition failure
  • Faulty engine system

Like all vehicles, issues can occur. It is very important to address these common problems with your quad bike as soon as you notice them. If not, they can lead to hazards.

The most common hazards with quad bikes are:

  • thrown off the quad bike due to overturns or after loss of control
  • collisions, for example with trees or other vehicles
  • trapped under an overturned quad bike
  • pedestrians hit or run over by quad bikes

Some other uncommon problems quad bike are:

  • lack of training
  • lack of experience
  • incorrect head protection
  • excessive speed
  • carrying a passenger
  • unbalanced loads or overloading the quad bike
  • tipping on a bank, ditch, rut or bump
  • loss of control on a steep slope combined with other factors like poor ground or load conditions
  • towing excessive loads with equipment with no brakes
  • poor maintenance of the vehicle, leading to faulty brakes or incorrect tyre pressures

Everyone who owns anything with a motor has experienced that sinking feeling when you hit the ignition button and things don’t go quite as planned. While you’re ready to load up and hit the trail, your quad isn’t ready to go anywhere. So what’s up?

While ATV troubleshooting there are a few common issues that should be your first line of investigation. Here are three things to especially keep in mind.

Here are the common problems quad bikes:

1) BATTERY POWER is a common problem with quad bikes

If your quad bike or ATV doesn’t turn over when the ignition is engaged, your battery may be low on juice.

A common cause is the lights were left on.

Fortunately, battery issues are normally easy to resolve.

To test the battery, use a multi meter from which you can purchase from Amazon here

You can use a multi meter to check for an output of 12V. If there is a low reading then it’s time to charge your battery.

Do so by hooking the terminals to a battery booster via alligator clips on the charging cables and go make yourself a sandwich while you wait. If the battery doesn’t charge, or continues to lose a charge time and time again, it may be time to install a whole new one.

2) IGNITION failure is a common problem with quad bikes

Where there’s fuel, there must be spark in order to get your motor running. If an ATV motor turns over, but doesn’t start, and the battery seems to be fine; it’s time to check out your ignition system.  

First, check out your spark plugs via a physical inspection. Look for any corrosion or gunk on the plug itself, and ensure that there is a small gap present in the spark gap of the plug. If the plug looks out of sorts, replace it. Otherwise, you can use your multimeter to test the plug and see whether or not a spark is present. Other parts of the ignition system, including the ignition coil and capacitor discharge ignition (CDI) can also fail, however are far less likely to. Refer to your owner’s manual for the best methods to troubleshoot these components.

3) Faulty ENGINE SYSTEM is a common problem with quad bikes

Failures within the engine system can be tougher to put your finger on due to the high volume of mechanical parts required to make it all run.

Starts and stalls, or a complete lack of engine action could be caused by simple fixes like a clogged air filter or exhaust, or more in-depth issues such as blocked fuel lines or over-fueling causing carburetors to flood.

Do-it-yourself’ers may be comfortable checking for issues within the engine system, while others may find that a trip to a mechanic is better suited for their needs.

Regardless of whether you choose to take care of the most common ATV issues yourself, or seek the help of a professional, it’s always handy to have an owner’s manual and be familiar with the basics of how your machine operates.
