Z900rs Running High Temperatures

Z900rs Running High Temperatures

Some bike owners have reported high-temperature issues while running in normal conditions. It is possible to identify these high temperatures by the temperature gauge of the motorcycle. High temperatures can happen by several factors, including poor quality fuel and riding at higher altitudes.

Maintaining your motorcycle and performing routine maintenance regularly is important to avoid this problem. Additionally, it is advisable to lower the cold idle from 2500 to 1500 rpm to reduce the risk of engine wear and decrease operating Service costs. By taking these simple steps, you can ensure your motorcycle runs reliably and efficiently every time you ride it.

Uncomfortable Seat

The Kawasaki Z900RS is a track-focused motorcycle built to be ridden hard and long. Some riders have reported numbness and fatigue after riding the bike for long periods due to the terrible fuel range and lack of comfort in the seat. The acceleration to freeway speed is also not as smooth as desired. However, installing aftermarket seats with better cushioning and support for longer rides is an option.

This will greatly improve the overall comfort and reduce fatigue. Additionally, the handlebar is 65 millimetres higher and 35 mm closer to the rider than the basic Z900s, adding more stability and control while riding. Overall, making these changes and riding the bike within its parameters will help ensure that I have a safe and enjoyable ride.

Low Idling Rpm

The Kawasaki Z900RS has experienced a low idling RPM issue, resulting in the engine cutting out. The low idling RPM can happen to the fuel quality used, as Kawasaki suggested. If you are experiencing this issue and want to fix it, consider using a high-quality fuel such as kerosene or diesel. The revving rev range of the Z900RS may also be lower when it is hot and higher when cold.

To increase the engine’s performance, Kawasaki has re-tuned the engine to deliver torque earlier in the RPM range and higher top speeds. Overall, this issue highlights the importance of using high-quality fuel and taking care of your ride to ensure it performs optimally every time.

Brake Defects


The Kawasaki Z900RS motorcycle faced recall due to a potential brake defect. The rear sprocket brake assembly may have a fault in which the brake hose and rear wheel rotation sensor lead may touch the rear tire, resulting in damage and potential loss of braking performance.

Riding on rough roads or at high speeds can significantly increase this issue. If this issue occurs, the braking effectiveness may fail, posing an accident risk to the motorcycle rider. Kawasaki Motorcycles Australia has initiated a recall of 132 retro-styling Z900RS models to address this issue.

Rear Shock Absorber Issues

The 2017-2018 Kawasaki Z900 series faced a recall for rear shock absorber issues. This issue could lead to inconsistent rear suspension performance and decreased braking performance. In response to this issue, it provided motorcycle owners free inspections and repairs from their local Kawasaki dealership.

The rear brake hose and wheel rotation sensor lead may touch the rear tire on certain models, potentially resulting in loss of braking performance due to brake fluid leakage or the ABS indicator light illuminating and the speed not displayed on the meter.

Kawasaki has updated their RS model to prevent this issue with a shorter first gear and taller final gear for easier cruising. Additionally, motorcycle bike owners can ensure their bike has the latest updates by checking the engine serial number label or contacting their local Kawasaki dealership.

Loud Banging Noise And Jerking

There have been several reported issues with the Kawasaki Z900RS, including a loud banging noise and jerky performance when engaging first gear. Sometimes, this issue arises from a worn clutch cable or transmission damage. The loud banging noise and jerky performance can happen due to poor maintenance and an incorrectly adjusted clutch cable.

Additionally, problems with the engine’s transmission, such as a clunky gear change, are common in the motorcycle. The power delivery of the Kawasaki Z900RS is aggressive from a closed throttle, which can lead to transmission issues. Overall, maintaining your vehicle and making sure all components are working properly is key to preventing problems like these from occurring.

Defective Cooling Fan Sensors

A common issue with the Kawasaki Z900RS motorcycle is defective cooling fan sensors, which cause the engine to overheat. If the cooling fan sensor is not working, the engine can overheat, leading to more serious problems. Regular maintenance of cooling fan sensors can help prevent this from happening.

Ignoring the issue of defective cooling fan sensors can lead to collisions and damage to the motorcycle. Instead, addressing any issues with the cooling fan sensor and taking the necessary steps to maintain average fuel consumption and repair the motorcycle is important. This will help ensure safe riding and avoid costly repairs or accidents.

Engine Overheating

Engine Overheating

Overheating the engine is a common problem that often occurs in a motorcycle. If you are experiencing overheating of your motorcycle’s engine, there are several things you can do to address the issue and prevent it from recurring. One of the most common causes of engine overheating is a clogged radiator. You can easily prevent this by regularly cleaning the radiator.

In addition to a clogged radiator, defective cooling fan sensors can trigger overheating in Kawasaki Z900RS motorcycles. To help prevent this, replace the radiator, head gasket, and cooling fan sensors. The chain on my bike is crucial for transferring power from the engine to the wheels.

Lack Of Fuel Gauge

A lack of a fuel gauge in the Kawasaki Z900RS can cause riders to be unaware of the amount of fuel left in the Tank range. This can be dangerous, as riders might ride long without realizing how much fuel is left. Many UTV owners have reported experiencing this problem with their Kawasaki KRX 1000s.

A fuel gauge in the Kawasaki KRX 1000 can lead to deadly accidents if riders ride for long periods without realizing how much fuel is left in the tank. The Z900RS does not have a fuel gauge as part of its standard features, and riders need to pay attention to the gauge and ensure they always have enough fuel to return home safely.

Belt Errors

Belt errors are common in Kawasaki Z900RS. If you notice an irregular noise from your motorcycle or see smoke coming from the rear of the bike, it may indicate a belt failure. To prevent wear and tear on belts, replacing them regularly is important. If your belt needs replacement, ensure that the correct one is installed and tensioned properly.

You can also ensure the clutch cable isn’t tight enough and kinked, which can lead to transmission problems. Lastly, maintain your motorcycle and perform regular maintenance to keep it running smoothly. The YFZ 450 showcases a bit of throttle abruptness. The average seat height is lower compared to others.

Clunky Gear Change

Clunky Gear Change

Riders of Kawasaki Z900RS have experienced clunky gear changes when shifting from neutral to first gear. This can be caused by not refilling the gear oil or excessive wear on the transmission. The 2021 models of this bike have defective brake pads that can lead to collisions. Kawasaki has added a slipper clutch to combat this issue to regulate downshifts and improve gear changing.

Additionally, the company has shortened the first gear and increased the final gear to improve efficiency. By addressing these issues, Kawasaki is ensuring that its popular motorcycles remain safe and reliable for years to come. The exhaust system is crucial in determining the overall performance of off-road vehicles like the YFZ 450 and Raptor 700.
