Hose Replacement: Removing the old hose and installing a new one is often the best course for cracked or significantly worn hoses. This is usually a straightforward task that many users can perform with little difficulty.

Use of Quality Hoses: Instead of opting for generic options, high-quality replacement hoses can ensure a longer-lasting repair and a nicer overall performance.

6. Dying Engine and Fuel Problems

Dying Engine Issues

Compression Problems: Low engine compression can cause the engine to die. Perform a compression test to diagnose this issue. If compression is low, internal engine repairs might be necessary.

Faulty Ignition System: An unexpectedly dying engine may have ignition system problems. Inspect and fix components like spark plugs and ignition coils to ensure they’re in top condition.

Overheating Due to Bad Water Circulation: Check the cooling system to see if the engine is overheating and dying. Make sure there’s no bad water circulation, and fix any issues with the radiator or coolant.

Fuel Problems

Clogged Fuel Lines or Filters: Clogged lines or filters can restrict fuel flow, causing the engine to run poorly or die. Remove and clean or replace these components to ensure smooth fuel delivery.

Contaminated Fuel: Bad fuel can cause numerous running issues. Drain the old fuel and put in fresh, high-quality fuel.

Carburetor Issues: A dirty or poorly adjusted carburetor can disrupt fuel delivery, leading to engine problems. Cleaning and properly adjusting the carburetor can often fix these issues.

Fuel Pump Malfunction: If the fuel pump is not working correctly, it can’t supply enough fuel to keep the engine running. Inspect the fuel pump and fix or replace it if necessary.

7. Braking Problem


  • One common issue faced by Arctic Cat DVX 400 owners is braking problems.
  • The most common cause for this problem is a lack of proper maintenance and neglect to check the brake system regularly.
  • Another possible culprit could be worn-out brake pads or rotors, which can significantly affect the stopping power of your ATV.
  • Low brake fluid levels or air bubbles in the brake lines can also lead to braking issues.
  • Compression problems in the engine can also affect the braking system, as it may not be able to provide enough power to stop the vehicle efficiently.


  • If you are experiencing any of these problems, first and foremost, check your brake system and ensure it is well-maintained.
  • If your brake pads or rotors are worn out, they must be replaced immediately with new ones to restore proper braking performance.
  • It is also crucial to regularly check and adjust the brake fluid levels to avoid any potential issues.
  • In case of air bubbles in the brake lines, bleeding the brakes can help remove them and restore proper functioning.
  • If your engine runs poorly, it can also result in inadequate braking power. So, make sure to address any engine issues to improve overall vehicle performance.
  • Additionally, be mindful of where you ride your ATV, as riding through bad water or mud can cause dirt and debris to accumulate on the brake pads, affecting their grip.

8. Seat Quality and Plastics

Plastic Quality

  • A common problem in ATVs.
  • Plastics are prone to breaking quickly, especially in off-road, muddy conditions.
  • Specific parts like fender and heel guards are not durable.

Seat Comfort

  • The seat is not very comfortable for long durations.
  • It might require additional cushioning pads for better comfort.
  • Comfort levels can vary based on personal preferences.


Replacing Parts: Replacing the plastics and seat is a potential solution.
This option can be expensive.

Aftermarket Solutions: Consider aftermarket parts or additional cushioning for the seat.
Look into more durable alternatives for plastics from third-party manufacturers.

Personal Preferences: some users may find it adequate without modifications.

Community Advice: Consult ATV repair specialists or join dedicated forums and communities for tailored advice. DIY fixes and suggestions from other ATV enthusiasts may offer practical solutions.

9. High Oil Consumption


  • High oil consumption can result in various issues, including reduced engine performance and increased emissions.
  • It can also lead to problems with the fuel system, such as clogged fuel injectors and filters.
  • Constantly monitoring and refilling oil levels can be time-consuming and costly.
  • Excess oil consumption may indicate underlying engine issues, which can be expensive to repair.
  • It can also cause damage to other components of the vehicle, such as the exhaust system and spark plugs.


  • Regularly checking and replacing faulty parts in the engine can help reduce oil consumption.
  • Proper maintenance of the fuel system, including cleaning or replacing filters and injectors, can also improve oil consumption.
  • Using high-quality oils and additives designed for high-mileage engines can help reduce oil consumption.
  • Seeking professional assistance to diagnose and address underlying engine issues can prevent excess oil consumption.
  • Following the manufacturer’s recommended maintenance schedule can help prevent potential engine problems that lead to high oil consumption.

10. Overheating Issues


  • The Arctic Cat DVX 400 is known for its powerful performance and smooth ride, but it also has some common overheating issues that can occur.
  • One of the main causes of overheating in this model is a malfunctioning fuel petcock, which controls fuel flow from the tank to the engine. If it is not functioning properly, it can lead to an insufficient fuel supply and cause the engine to overheat.
  • Another common issue is a faulty cylinder head gasket, resulting in a combustion leak and engine overheating. This will require replacement to prevent further damage.
  • A clogged or damaged fuel tank can also contribute to overheating as it may restrict fuel flow to the engine, causing it to work harder and overheat. It is important to regularly check and clean the fuel tank to avoid this issue.
  • Throttle-related problems can also cause overheating in the Arctic Cat DVX 400. If the throttle is not functioning properly or becomes stuck, it can lead to excessive engine revving and overheating.


  • If you suspect that the fuel petcock is the cause of overheating, it is best to replace it with a new one. This is a relatively easy and inexpensive fix.
  • In the case of a faulty cylinder head gasket, a replacement will be needed. It is important to address this issue as soon as possible to prevent further damage to the engine.
  • Regular fuel tank maintenance and cleaning can help prevent clogs and damage. It is also recommended to use high-quality fuel to avoid any potential issues.
  • Throttle issues can be resolved by adjusting or replacing the throttle cable. However, if you cannot do so yourself, it is best to take your ATV to a professional mechanic for proper diagnosis and repair.
  • Regularly checking and maintaining your ATV’s cooling system is important to prevent overheating. Monitor the coolant levels and ensure the radiator fins are clean and debris-free.
  • Another helpful tip is to avoid riding your Arctic Cat DVX 400 in extreme temperatures or for extended periods without breaks. This can strain the engine and increase the risk of overheating.
