Tire and Spacing

The Brute Force 750 also comes with big tires to provide extra stability and traction, making the ATV appropriate for even the most demanding off-road conditions. Another plus for the ATV is its spacious and comfortable seating area. The combination of big tires and spacious seating area makes all the difference when driving on extremely rough terrains. Furthermore, buyers also acknowledge the fact that the Brute Force 750 is relatively easy to service and maintain.

Kawasaki Brute Force 750 Known Issues & Possible Fixes

Diagnosing The Causes And Solutions Of Common Kawasaki Brute Force 750 Issues

While Kawasaki might have designed an incredibly powerful ATV in the Brute Force 750, that doesn’t mean the vehicle is perfect. Upon reviewing reports, forums, and reviews, we’ve zeroed in on the top Kawasaki Brute Force 750 problems.Let’s get started.

Belt Slipping

The most common complaint from buyers of the Brute Force 750 is about the ATV’s belt getting loose. This problem will not only cause the vehicle to perform poorly, but it’s also quite dangerous. There are a variety of things that can cause the machine’s belt to slip but, a notable cause is a gradual deterioration with time. For an off-road-ready ATV like the Brute Force 750, its belts can stretch and loosen over time, especially if you drive it frequently over mud and water.

Another primary reason for a loose belt is a lack of lubrication. If you fail to lubricate your drive belt regularly, it will become excessively dry and dirty, resulting in slipping. Lastly, improper tensioning might also cause the belt to slip. If the ATV’s tensioner pulley isn’t adjusted correctly, it will put too little or too much tension on the drive belt, causing it to slip.


The first move you need to make is to check the state of the ATV’s belt. If it’s stretched or worn out, then it’s time for a quality replacement. You can often tell if a drive belt is worn out by looking for fraying, cracks, or other indications of wear.

If the belt is in excellent condition but it appears to be loose, you need to tune the tensioner pulley. This process is quite simple and can be carried out with standard tools. Firstly, locate the tensioner pulley’s adjustment bolt and loosen it. Afterward, tighten the belt by turning the adjusting nut from left to right. And just like that, you’ve solved the problem.

Hard Starts

Another common issue associated with this ATV is that it usually has trouble starting. There could be a couple of reasons for this, ranging from electrical to engine issues. However, the first and most obvious reason is that there might not be enough fuel entering the vehicle’s engine. The Kawasaki Brute Force 750 fuel injection problem causes the engine to stall before starting and increases fuel consumption.

Besides that, a faulty wiring system, dying battery, and dirty spark plugs can also be causes of the ATV’s engine not starting. Therefore, to pinpoint the reason for the Brute Force 750’s slow start, you must conduct a proper vehicle inspection.


You simply have to clean the fuel injector to fix the vehicle’s fuel injection problems. A clogged fuel injector could hinder fuel from getting into the ATV’s engine. Therefore, the best way to deal with a jammed fuel injector is by removing it and having it professionally cleaned or replaced. If this doesn’t seem to solve the issue, consider taking the Brute Force 750 to an experienced mechanic for further inspections and repairs.

For a faulty wiring system, you will have to properly inspect your ATV’s wiring to determine what’s wrong. If you discover that a wire has been cut or is barely hanging on by some strands of copper wire, then you have to repair it yourself with a soldering iron.

If you think that your ATV’s hard start is being caused by a dirty spark plug, then you have to clean it. While it’s often better to just replace the fouled spark plugs, you can always try cleaning it at first with a plug cleaner and a wire brush.

Corrosion In Its Connectors

This issue affects several users primarily because the quad is constantly exposed to different elements when driving outdoors. If the electrical system of the Brute Force 750 is exposed to mud or water, it is susceptible to corrosion and other related issues. Ideally, Once the connectors are corroded, the vehicle’s electrical functionality will be faulty.

Some of the common symptoms of damaged or corroded connectors include;. They are;

  • Overheating engine due to a damaged fan.
  • Blown fuses.
  • Engine delays when 4-wheel drive is activated and restarts only in 2-wheel drive.
  • The engine kick-starts without an ignition key (signaling a failing sensor).
  • Flashing check-belt-light.


Leaving the Brute Force 750 connectors wet will result in damaged wiring and corrosion. Therefore, you have to check the connection for any form of corrosion regularly.

After every drive, open up the connector panel and inspect it for any water or mud that might have gotten in, and ensure to clean the internal components. This is the most effective way to prevent corrosion to the Brute Force 750’s connectors

Knocking Noises

Another notable issue with the Brute Force 750 is its irritating knocking noises. While it’s pretty normal for an ATV to be a bit noisy, the rattling noises the Kawasaki’s Brute Force 750 makes are difficult to overlook.

The leading cause of this rattling sound is the ATV’s suspension. If the shocks are not adequately adjusted or damaged, your ATV will definitely make knocking noises. In addition, if your vehicle’s drivetrain is imbalanced, your machine will make rattling noises. Finally, if the frame is damaged or bent, you will experience loads of rattling noises while driving.


The first step to fix this problem is adjusting the shocks if necessary. Additionally, you have to check the suspension links and arms for any wear or damage. Consider replacing these parts if you notice any defects.

Leaf springs, an imbalanced wheel, or worn-out bearings often cause an imbalanced drivetrain. Therefore, you have to bring in a professional to calibrate the drivetrain and replace any worn-out components. If you still notice the rattling noises even after inspecting and fixing these things, then you have to contact a professional to carry out additional diagnosis and repairs.

Non-functional Radiator Fan

The last notable problem that can occur with your Brute Force 750 is its radiator fan stopping abruptly. This is a major problem and it can occur from a number of reasons, but the primary culprit is your ATV’s engine overheating. The Brute Force 750 motor cannot function without a form of a cooling system, and this is accomplished by the radiator fan, which keeps vital components at a low temperature to prevent heat damage.

Basically, owners complain about the radiator fan suddenly stopping or not starting automatically. This can be due to a damaged circuit breaker that stops the fan at unexpected periods.


There are a couple of things you can do to troubleshoot this issue. For starters, inspect the fan’s fuse and ensure it isn’t blown. However, if it is blown, replace it immediately with a new one. Next up, ensure that power is getting into the fan motor. If it isn’t, then you’ll have to inspect the wiring harness for short or loose wires.

Finally, inspect the fan motor itself and ensure that it isn’t damaged or even seized up. If it has charred corners or smells burnt, then you will have to replace it with a new one.


The Kawasaki Brute Force 750 is in high demand for a good reason. Overall, the ATV has an engine with the ability to deliver the best performance for all your casual riding or outdoor adventures. As you might have noticed, most of these complaints are caused by natural wear and tear and neglect on the part of buyers. However, these can be prevented with proper maintenance and care, as well as resolving any issue that arises as quickly as possible.
