FAQs
Do I need to soak the friction plates before installation?
Yes, it is standard practice and highly recommended to soak the new friction plates in fresh engine oil for at least 30 minutes (or as per manual instructions) before installation. This ensures they are lubricated upon first use, preventing damage and premature wear.
Can I reuse my old clutch springs?
It is best practice to replace the clutch springs with the new ones provided in the kit. Over time, springs can lose their tension, affecting clutch performance. Using new springs ensures consistent pressure.
What type of oil should I use?
Use a high-quality motorcycle-specific oil that is suitable for wet clutch applications. Refer to your Yamaha YZ125's owner's manual for the recommended oil viscosity and specifications.
Is this kit compatible with other Yamaha models?
This specific kit is designed for the Yamaha YZ125 models from 2002-2004. Compatibility with other models is not guaranteed and would require verification.
How often should I replace my clutch?
The frequency of clutch replacement depends heavily on riding style and conditions. For aggressive riding like motocross, inspections and potential replacement may be needed more often. Refer to your service manual for recommended inspection intervals.
What is the difference between this kit and an OEM replacement?
This Apico kit offers OEM quality in terms of function and durability but is often manufactured with materials and processes that may provide an enhanced feel and performance, aiming for a 'factory team' quality.
Troubleshooting
Clutch slipping after installation
Ensure all plates were installed correctly, in the right order, and soaked in fresh oil prior to installation. Verify that the clutch springs are tightened evenly and to the correct torque specification. Check that the clutch cable free play is set correctly.
Clutch not disengaging fully
Confirm that all friction and steel plates are installed correctly and not warped. Double-check that the clutch springs are not overtightened, which can prevent full disengagement. Ensure the clutch pushrod is seated properly.
Difficulty shifting gears
This can be related to clutch disengagement issues. Re-check the installation and adjustment of the clutch components and cable. Ensure the engine oil level is correct and that the oil is suitable for wet clutches.
