5. Setup and Installation
Follow these steps to install your Kewig M22-C2 Motorcycle Fork Stem Phone Mount:
- Prepare the Fork Stem Hole: Identify the fork stem or Triple Tree Stem Yoke Center hole on your motorcycle. Select the appropriate spacer (small for 12-18.5mm, large for 18.5-25.4mm) that best fits the diameter of your motorcycle's fork stem hole.
- Insert the Base: Insert the fork stem ball base with the selected spacer into the fork stem hole. Ensure it sits securely.

- Attach the Phone Mount Body: Insert the ball joint of the phone mount main body into the ball socket nut.

7. Maintenance
To ensure the longevity and optimal performance of your phone mount, follow these maintenance guidelines:
- Regular Cleaning: Wipe the mount regularly with a soft, damp cloth to remove dust and grime. Avoid harsh chemicals or abrasive cleaners.
- Check Tightness: Periodically check all screws and nuts, especially the fork stem base and ball socket nut, to ensure they remain securely tightened. Vibrations from riding can sometimes loosen components over time.
- Inspect for Wear: Examine the silicone pads and telescopic arms for any signs of wear or damage. Replace components if necessary to maintain secure phone grip and shock protection.
- Lubrication: If the rotation mechanism becomes stiff, a small amount of silicone-based lubricant can be applied to the ball joint.
8. Troubleshooting
If you encounter any issues with your phone mount, refer to the following common problems and solutions:
- Mount feels loose in the fork stem:
Solution: Ensure the correct spacer size was used for your fork stem hole. Re-tighten the fork stem ball base using the Allen wrench to expand the spacer fully. - Phone is not held securely:
Solution: Verify that your phone's dimensions (4.0-6.9 inches, thickness less than 16mm) are within the compatible range. Ensure the one-push lock mechanism fully engages when placing the phone. Adjust the width of the phone holder by adjusting the screws on the four holder feet if needed. - Phone mount rotates or shifts during riding:
Solution: Tighten the ball socket nut firmly. If the issue persists, ensure the fork stem base is also securely installed and not rotating. - Difficulty inserting or removing phone:
Solution: Check for any obstructions. Ensure the quick-release button is fully pressed when removing the phone. If the mechanism feels stiff, clean it and apply a small amount of lubricant if necessary.
