Kawasaki Concours 14 Transmission Problems

Kawasaki Concours 14 transmission fails due to material defect or abuse by the rider. Check the linkage and clutch lever free play to troubleshoot the issue.

Check for any internal transmission issues. Oil change could troubleshoot some issues too.

Transmission Failure Reasons

Material Defect

A bad production batch of gears might infiltrate the supply chain with substandard hardness or improper heat treatment.

This could lead to premature wear and eventual breakage after accumulating miles.


Severe clutch slipping combined with excessive throttle blipping could theoretically overload and damage internal gear teeth over time via shock loading.

However, most documented cases did not involve obvious rider abuse.

While it’s challenging to pinpoint the exact cause, a combination of material defects and potential abuse might contribute to transmission issues.

Troubleshooting Guide

Below are a few instructions for troubleshooting transmission problems on Kawasaki Concours 14.

Checking the Linkage

Inspect the output shaft to ensure the bolt on the linkage is not loose.

Regularly lubricate all pivot joints on the linkage and the shift lever to ensure smooth operation.

Clutch Lever Free Play

Ensure there is not too much clutch lever free play, as excessive play might hinder the clutch from fully disengaging.

Properly pulling the clutch in all the way is crucial for smooth shifts, and some riders even upshift without the clutch with precise timing.

Oil Selection

Experiment with different oils to find the one that works best for smooth shifting.

Some riders recommend Mobil One Racing 4T for improved performance.

Internal Transmission Issues

If external solutions don’t work, consider internal issues such as a bent shifting fork or a broken shift return spring.

Oil Change as a Troubleshooting Step

Some riders have experienced improved shifting performance after changing the oil.

Experimenting with different oil brands and types can provide valuable insights.

Solving Shifting Issues on Kawasaki Concours 14

The distinct “clunk” sound during gear changes became a frustration. Following are a few ways to fix shifting issues on Kawasaki Concours 14.

Shift Lever Position

Adjusting the shift lever position is crucial. A slight adjustment can make a noticeable difference, preventing preloading and clunking during shifts.

Shifting with Authority

Shift with authority for smoother transitions. Instead of gently clicking into gear, these bikes respond better to a firm and deliberate shift.

Throttle Control

Smooth shifts come with a more deliberate and controlled application of the throttle. Finding the right balance is key.

Idle RPM Adjustment

Temporary improvement can be achieved by increasing idle RPM to 1300. For a more permanent fix, consider professional reflashing options.

Oil Change and Synthetic Oil

Switching to synthetic oil, especially after an oil change, can result in a slicker gearbox. Experimenting with different synthetic oils is recommended.

Inconsistent Shifting Across Gears

Inconsistent shifting, especially between first and second gears, can be frustrating. Riders have shared insights and solutions to address this issue.

Fluid Maintenance

Regular fluid changes and flushing of the master and slave cylinders can help remove contaminants and air in the system.

Clutch Star Springs

Some riders have experienced issues with clutch star springs, leading to inconsistent shifting. Checking and potentially replacing these springs might resolve the problem.

Hydraulic Clutch System

Flushing the hydraulic clutch system may not always yield improvement. Disassembling the clutch and addressing broken components could be necessary.

Transmission Preventive Maintenance

Regularly checking the linkage is a crucial step—inspecting the output shaft for a secure linkage bolt and lubricating all pivot joints ensure smooth operation.

Maintaining the right clutch lever free play is essential for smooth shifts, and experimenting with different oils, like Mobil One Racing 4T, can significantly impact performance.

For those frustrated by the distinct “clunk” sound during gear changes, adjusting the shift lever position can make a noticeable difference.

Shifting with authority and a more deliberate application of throttle control are recommended for smoother transitions.

Temporary improvement can be achieved by adjusting the idle RPM to 1300, while a more permanent fix might involve professional reflashing options.

Inconsistent shifting across gears, especially between the first and second, can be addressed through fluid maintenance—regular changes and flushing of the master and slave cylinders.

Some riders have identified issues with clutch star springs, suggesting checking and potentially replacing these springs as a solution.

In cases involving the hydraulic clutch system issues, flushing may not always yield improvement, requiring a deeper dive into disassembling the clutch and addressing broken components.
