The Arctic Cat VLX 700, a popular all-terrain vehicle (ATV), is celebrated for its power and ruggedness. However, like any machine, it's not immune to issues. Understanding these potential problems, from engine quirks to suspension struggles, is crucial for owners looking to maintain their ride and keep it running smoothly for years to come. This article dives deep into the common issues plaguing the VLX 700, offering insights and potential solutions to help you troubleshoot and enjoy your ATV to the fullest.

Engine Troubles: When the Roar Turns into a Sputter

The heart of any ATV is its engine, and the VLX 700 is no exception. Unfortunately, engine problems are among the most frequently reported issues by owners. Let's explore the usual suspects.

Fuel Delivery Issues:

  • Clogged Carburetor: This is a common culprit, especially if the ATV has been sitting idle for extended periods. Old fuel can break down and leave deposits that clog the jets and passages within the carburetor. Symptoms include difficulty starting, rough idling, and poor performance at higher speeds. Cleaning or rebuilding the carburetor is often the solution.
  • Fuel Pump Malfunctions: The fuel pump is responsible for delivering fuel from the tank to the carburetor (or fuel injectors in later models). If it's failing, you might experience stalling, hesitation, or complete engine shutdown. Testing the fuel pump's output pressure is a good way to diagnose this issue.
  • Fuel Line Problems: Cracked, kinked, or deteriorated fuel lines can restrict fuel flow, leading to similar symptoms as a faulty fuel pump or clogged carburetor. Inspect the lines carefully for any signs of damage. Replacing old or damaged fuel lines is a relatively inexpensive fix.
  • Dirty Fuel Filter: A clogged fuel filter restricts fuel flow to the engine. It is a simple and inexpensive part to replace. Regular fuel filter replacement is a key maintenance item.

Electrical Gremlins:

  • Faulty Stator: The stator generates the electricity needed to charge the battery and power the ignition system. A failing stator can cause a weak spark, leading to starting problems or engine misfires. Testing the stator's output with a multimeter is essential for diagnosis.
  • Bad Ignition Coil: The ignition coil amplifies the voltage from the stator to create a spark at the spark plug. A weak or failing coil can result in a weak spark, causing similar symptoms to a faulty stator.
  • Spark Plug Issues: A fouled or worn spark plug can prevent the engine from starting or running properly. Regular spark plug replacement is a simple maintenance task that can prevent many problems. Ensure you are using the correct spark plug specified for your VLX 700.
  • Loose or Corroded Connections: Grounding issues and corroded connections are common in ATVs, especially those frequently exposed to mud and water. These can cause a variety of electrical problems, including starting issues, erratic instrument panel behavior, and even complete electrical failure. Thoroughly inspect and clean all electrical connections, paying particular attention to the grounding points.

Overheating:

  • Coolant Leaks: Leaks in the radiator, hoses, or water pump can lead to overheating, which can cause serious engine damage. Regularly check the coolant level and inspect for any signs of leaks.
  • Clogged Radiator: Mud, debris, and insects can clog the radiator fins, reducing its ability to dissipate heat. Regularly cleaning the radiator with a soft brush and water can help prevent overheating.
  • Faulty Thermostat: The thermostat regulates the flow of coolant through the engine. A stuck or malfunctioning thermostat can prevent the engine from reaching its optimal operating temperature or, conversely, cause it to overheat.
  • Water Pump Failure: The water pump circulates coolant throughout the engine. A failing water pump will prevent proper cooling and cause overheating.

Other Engine-Related Issues:

  • Valve Problems: Worn or improperly adjusted valves can lead to loss of compression, resulting in poor performance and difficult starting.
  • Piston and Cylinder Wear: Over time, the piston rings and cylinder walls can wear down, leading to loss of compression and engine blow-by. This usually requires a more extensive engine rebuild.

Transmission Troubles: Shifting Gears and Avoiding Grinds

The transmission is another critical component of the VLX 700, responsible for transferring power from the engine to the wheels. Here are some common transmission-related issues:

  • Difficulty Shifting: This can be caused by a variety of factors, including a worn shift linkage, low transmission fluid, or internal transmission damage.
  • Slipping Gears: This occurs when the transmission pops out of gear under load. It's often a sign of worn clutch plates or internal transmission damage.
  • Noisy Transmission: Grinding, whining, or clunking noises from the transmission can indicate worn gears, bearings, or other internal components.
  • Leaking Seals: Leaks from the transmission seals can lead to low fluid levels, which can damage the transmission.

Preventative Maintenance is Key: Regularly checking and changing the transmission fluid, as well as inspecting and lubricating the shift linkage, can help prevent many transmission problems.

Suspension Woes: Bumps, Bruises, and Bottoming Out

The suspension system is crucial for providing a comfortable and controlled ride. Here are some common suspension-related issues:

  • Worn Shocks: Over time, the shocks can lose their damping ability, resulting in a bouncy or uncontrolled ride.
  • Broken Springs: Broken springs can cause the ATV to sag on one side or bottom out easily.
  • Worn Bushings: Worn bushings in the A-arms and other suspension components can cause play and looseness in the suspension, leading to poor handling.
  • Ball Joint Problems: Ball joints connect the A-arms to the wheel hubs. Worn or damaged ball joints can cause excessive play in the steering and handling.

Regular Inspection and Lubrication: Regularly inspecting the suspension components for wear and damage, as well as lubricating the grease fittings, can help extend the life of the suspension system.

Electrical System Quirks: Beyond the Engine

While we've touched on engine-related electrical issues, the VLX 700 can also experience problems with other electrical components:

  • Battery Issues: The battery can fail due to age, lack of maintenance, or excessive drain. Regularly check the battery's voltage and electrolyte level (if applicable).
  • Lighting Problems: Burnt-out bulbs, faulty wiring, or a bad switch can cause lighting problems.
  • Instrument Panel Issues: The instrument panel can malfunction due to loose connections, damaged wiring, or a faulty display.

Proper Wiring Practices: When making any electrical repairs or modifications, always use proper wiring techniques and ensure all connections are secure and protected from the elements.

Common Arctic Cat VLX 700 Issues: A Summary

Here's a quick recap of the most common problems you might encounter with your Arctic Cat VLX 700:

  • Engine Problems: Fuel delivery issues (clogged carburetor, fuel pump failure), electrical problems (faulty stator, ignition coil), overheating.
  • Transmission Problems: Difficulty shifting, slipping gears, noisy transmission, leaking seals.
