Common Problems of Kawasaki Brute Force 750:

Kawasaki Brute Force with 749CC displacement is a true off-roading monster. You can enjoy its performance thoroughly, once you know Brute Force 750 common problems and their solutions.

Problem 1. Belt Slipping

The rider may ride the Brute Force 750 on off-road and dangerous roads. Therefore, dust and mud might touch and enter the vehicle’s inner parts. The water or mud enters the belt and causes belt slips. However, you won’t find belt slips all the time.

Causes of belt slip:

There are several reasons behind the belt slip of the Kawasaki Brute Force 750. The water and mud may enter the belt in many ways. But water is not the only reason for slipping belts. Some possible causes may be:

• When you ride in dry conditions, debris and dirt may cause the belt to slip 
• The exceeding power can force the belt to slip 
• The drive belt may be worn out or damaged 
• Improper belt tension settings 

Symptoms of the belt slipping:

• Vehicle’s performance will drop 
• Engine RPM becomes higher than usual, even at low- speed
• There may a burning odor from the clutch area 
• Slipping belts also produce noise and vibration from the clutch area
• In sticky situation, when you accelerate the vehicle, the drive belt might slip away 

Solution of Slipping Belt:

You should replace the worn, damaged, or glazed belt with the new one. You should replace the belt and adjust correctly. While installing a new belt, remember the following tips:

• Adjust the belt deflection correctly
• Make sure to set the clutch springs correctly 
•  The flyweights should move freely
• Clean the sheaves surface
• Set the correct torque

You may install mudguards and protective accessories. It will protect the belt from entering water and mud. Lastly, you should try to lift fewer loads with the Brute Force. If you put too much weight on it, the belt may not function properly and start slipping away. 

Problem 2: Corrosion in the Connectors

Many Kawasaki’s Brute Force 750 riders may find corrosion problems in the connectors. When they ride outdoors, the quad is exposed to water and sustains corrosion. The corrosion can create electrical failure down the road.

Causes of Corrosion in the Connectors:

There are two BUSS connectors on the Kawasaki Brute Force 750 wiring harness. When water enters these connectors, it may cause corrosion. Also, salt, acid, or pollutants can trigger the corrosion process.  

On top of it, the oxidation may develop corrosion. Frequent temperature changes can cause condensation, too and it will result in corrosion. Sometimes loose connections may cause this problem in Brute Force 750. 

Symptoms of Corroded or Damaged Connectors:

• The vehicle will face poor electrical performance
• High resistance along the connection
• Blown fuses
• Corrosion creates unusual heat at the connection point
• At times, you will experience strange smell due to corrosion 
• Sparks or arching in the wiring section 

Solution of corrosion in the connectors:

There is a proverb that says, “Prevention is better than cure.”  So, you should follow some safety measures to stop any damage to the ATV connectors.  You can check the connectors of Brute Force 750 regularly. The liquids may leak after your rides. You must check out the liquids and clean them properly.

You have to check the corrosion on the BUSS connectors too. Sometimes you may find greenish corrosion under the connector cap. In this case, you have to clean it and seal the connection with a proper motorcycle corrosion cleaner. 

The older model of Kawasaki has built-in ability to fix issues of corrosion. But, new models do not have such functions. So, you have to bundle up the connectors and seal them separately, manually

Problem 3: Problems Engaging 4-Wheel-Drive Mode

The Kawasaki Brute Force 750 has two different modes. It provides both 4-wheel drive mode and 2-wheel drive mode. There is no problem in 2WD mode. However, you may find problems in 4WD mode.

Causes of the problems of engaging 4WD mode:

• The main cause of the problem engaging 4WD mode is water intrusion. When water enters the front differential, the clutch cannot control the engagement of 4WD
• The faulty switches, wiring, or sensors rm can also create the problem with 4WD 
• In cold weather, frozen water may also cause it to become stuck and obstruct the 4WD engagementIf there is a limited-slip differential or clutch packs. It will make it difficult to engage.

Symptoms of the 4WD engagement:

• The actuator doesn’t move an inch or make a peep.
• All fuses in Buss Connector
• Water intrusion in the wiring harness
• Water intrusion in the front differential
• The rider flips the switch to enter 4wd, but the indicator stays at 2wd

Solution of the engagement:

To fix the 4WD issues on the Brute Force, you have to look into the actuators. You will notice the 2WD/4WD lights flashing in one-second intervals. Therefore, you have to follow the manufacturer’s instructions to solve it.

• You also need to check the faulty switches and replace or repair them.
• If you find any fluids, you can also replace fluids by following the manufacturer.
• The rider must regularly engage and disengage the 4WD system to prevent the problem.
• It would help if you cleared the debris, mud, or other obstructing objects from the drive.
• After applying the above solution, you must consult a mechanic if your 4WD is disengaged.

Problem 4: Radiator Fan Not Working

In vehicles, motors generate power, and power generates heat. But there is a cooling device such as a radiator fan to run the motor properly. Sometimes, the radiator fan of Kawasaki’s Brute Force 750 may not function or be damaged.

Causes of not working the radiator fan:

The electric motor of the radiator may fail. The reasons for the failure of the motor are wear, overheating or electrical issues. If there is a blown fuse in the fan’s circuit, it can also cause the not working radiator fan.

The temperature sensor may become damaged. Therefore, the sensor sends the wrong signal to the radiator fan. It is another reason not to turn on the fan.

Symptoms of the dysfunction of the radiator fan:

• Check coolant level
• Thermostat connections are broken
• There is a problem with the radiator sensor
• Mud clogging up the radiator
• Rear Buss Connector dysfunction
• Problems in Circuit breaker

Solution of working radiator fan:

• You have to keep the radiator fan in an optimal state. Otherwise, it would damage the ATV on the whole.
• If there are any issues with blown fuses, you have to repair them.  
• The temperature sensors must be fixed to send the correct signal to the fan.
• You can also use a diagnostic scanner to find out the error of the cooling system.
• You can check the functioning of the radiator fan. You need to replace it with a newer one if there is any defect. You can expect to get the radiator from $25 to $30. 

Problem 5: Engine Takes Time to Start

Most of the rides of Brute Force 750 reported engine problems. When the weather is too cold, the engine takes some time to start. It may happen due to insufficient battery power.

Causes of delaying engine start:

A weak battery can result in taking a longer time to start. It does not provide enough power to the engine to start naturally. Sometimes defective wiring can also create the problem. The loose connections cannot make a quick spin to the engine. Therefore, the engine of the Brute starts late.

There may be clogged in the fuel filter. Therefore, sufficient fuel cannot reach the engine. It is also a reason for not staring at the engine normally. Moreover, low-quality fuel is also responsible for this issue. Sometimes, the sensor may not work and cause problems.

Symptoms of the delaying engine start:

• The engine takes longer time than usual to start
• Rough or slow cranking
• Unusual engine sounds such as knocking or rattling 
• Reduced engine power and performances
• Flashing issue in the security light

The solution to the delay in starting the engine:

• First, you need to find out the main cause of the issues. For this purpose, you must conduct a full ATV inspection. Then you will fix it correctly.
• You have to make sure that the battery has enough power 
• You might replace the faulty wires 
• Also, repair the engine connection 
• If the engine has insufficient fuel, you have to fill up your gas tank.
