Problem6: Power Loss And Idling

Power Loss And Idling

Power loss in Kawasaki-built engines is common. If the engine grows 5 to 7 years old, it will significantly lose its power loss issue and performance. It limits your uses of the UTV on hilly terrains and in heavy-duty tasks. Another common issue with Mule Pro MX is its idling problem. It refers to the UTV not starting when you keep it idle for a long period. 


  • Power loss problem takes place when you ride the UTV on too stiff hills. Also, riding on stiffer hills for an extended period is responsible for power loss.
  • The idling problem happens because of dirty air and fuel filters. Also, residues on the carburetor and spark plug are responsible.


  • During winter, continue pressing the UTV’s pedal for 20 seconds. It helps the utility vehicle to warm up properly and ignite the engine.
  • If you don’t use the vehicle for an extended period, cover it adequately to stop dust and residues. It helps you keep the vehicle in good condition.
  • When you switch on the vehicle after a few days or months, clean its carburettor, air, and fuel filter before starting it. Also, change the fuel for better performance.

Problem7: Loss Of Speed And Acceleration

The Kawasaki Mule Pro MX is a utility vehicle popular for its durability and versatility. However, owners may experience a loss of speed and acceleration over time, which can be attributed to several factors.

One possible cause is a worn-out drive belt. The drive belt is responsible for transferring power from the engine to the wheels, and if it becomes worn or damaged, it can result in a decrease in speed and acceleration. 


Fortunately, there are several solutions available to address this issue. Firstly, it is essential to check the air filter and ensure it is clean and debris-free. A clogged or dirty air filter can restrict airflow to the engine, reducing power and performance.

Regular cleaning or replacing the air filter is recommended to maintain optimal engine performance. Secondly, examining the Fuel Leak system is crucial. A clogged fuel filter or a malfunctioning fuel pump can restrict the fuel supply to the engine, causing a loss of speed and acceleration.

Regular maintenance and inspection of the fuel system can help prevent such problems. If any issues are detected, they should be repaired or replaced promptly.

Problem8: Transmission issues

Transmission issues

Transmission issues can be a common concern with the Kawasaki Mule Pro MX. The transmission system in this utility vehicle is responsible for transferring power from the engine to the wheels, allowing for smooth and efficient operation. However, some users have reported experiencing transmission problems with their Mule Pro MX models.

One of the issues that can arise is difficulty shifting gears, where the transmission may become stuck or fail to engage properly. This can lead to problems with acceleration and overall performance. Additionally, some owners have reported unusual noises from the transmission, such as grinding or whining, which can indicate internal damage or wear.


Transmission issues can be a common problem in Kawasaki Mule Pro MX vehicles. When faced with transmission problems, it is important to address them promptly to avoid further damage and costly repairs. Fortunately, there are several solutions available to tackle these issues.

Low fluid levels or dirty fluid can contribute to transmission problems. If the fluid level is low, replenishing it can resolve the issue. However, if the fluid is dirty or contaminated, it may be necessary to drain it and replace it with fresh fluid.

Another solution is to inspect and replace any worn or damaged transmission components. Over time, parts such as the clutch plates, gears, or bearings can wear out or become damaged, leading to transmission issues.

Problem9: Overheating

Although most UTVs have overheating problems, they are commonly seen in the Mule Pro MX. You will see the front seat getting too much heating when you ride the vehicle for an extended period. Also, the heat starts dissipating through the sides of the seat. Hence, it becomes unbearable for the rider to sit in the front seat. We have seen that the heat will rise over 45 degrees, so it is a severe problem.


  • Clogged radiators
  • Engine throttling


Check its radiator if you find the persistent overheating problem from the Mule Pro MX engine. Mostly, it becomes clogged and stops heat dissipation. So, the easiest way is to remove the radiator, clean and remount it.

  • Damages and residues on the spark plugs.
  • Clogs in the fuel filter as air stops passing through to the engine.
  • Problems with the vacuum system of the vehicle’s engine.


  • Check the spark plugs
  • Clean the fuel system
  • Inspect the ignition system
  • Verify the air intake system
  • Check for vacuum leaks
  • Test the fuel pump

Problem11: No Mirrors On The Sides:

A significant design problem of the Kawasaki Mule Pro MX is the lack of mirrors on both sides. Surprisingly, Kawasaki didn’t include any side mirrors for this vehicle. While you ride the UTV, this lack of side mirrors will limit your visibility significantly.

Riding the Mule Pro MX in rugged terrain makes this visibility issue more severe. You won’t know what’s coming from behind. So, it limits your riding’s smoothness and safety.


The only way to fix this side mirror problem is to install a new pair of mirrors on your Kawasaki Mule. You may choose the Kolpin UTV Side Mirror or Seizmik 18072 Pursuit Side View Mirror.
