2. Installation Instructions
Before beginning installation, ensure the motorcycle is securely supported and the front wheel is off the ground. Exercise caution when working with suspension components. If you are unsure about any step, consult a qualified mechanic.
- Prepare the Motorcycle: Safely lift the front of the motorcycle using a suitable stand to relieve pressure on the front forks.
- Locate Stock Adjusters: Identify the existing plastic fork adjuster knobs on the top of each fork leg.
- Remove Stock Adjusters: Carefully remove the stock plastic adjusters. This may involve unscrewing them or gently prying them off, depending on the specific fork design. Refer to your motorcycle's service manual for precise removal instructions if needed.
- Install Tusk Adjusters: Place the new Tusk Billet WP Fork Adjuster Knobs onto the fork legs. Ensure they seat correctly and are aligned.
- Secure Adjusters: Secure the new adjusters. They are typically designed to press fit or screw into place. Do not overtighten if screwing.
- Verify Installation: Once installed, gently attempt to turn the adjusters to confirm they are properly seated and functional.
- Lower Motorcycle: Carefully lower the motorcycle from the stand.

3. Operating the Fork Adjusters
These billet fork adjuster knobs allow for easy, tool-free adjustment of your WP forks. The markings on the knobs indicate the direction of adjustment:
- '+' (Plus) / Arrow Up: Turning the knob in this direction typically increases damping, making the suspension firmer.
- '-' (Minus) / Arrow Down: Turning the knob in this direction typically decreases damping, making the suspension softer.
Always make small, incremental adjustments and test the suspension feel after each change. It is recommended to adjust both fork legs equally to maintain balanced suspension performance. Refer to your motorcycle's owner's manual or suspension tuning guide for specific recommendations on adjustment ranges and settings.
4. Care and Maintenance
To ensure the longevity and proper function of your Tusk Billet WP Fork Adjuster Knobs, follow these simple maintenance guidelines:
- Cleaning: Regularly clean the knobs with a mild soap and water solution to remove dirt, mud, and debris. Avoid harsh chemicals or abrasive cleaners that could damage the anodized finish.
- Inspection: Periodically inspect the knobs for any signs of damage, wear, or looseness. Ensure they remain securely attached to the fork legs.
- Functionality Check: Occasionally turn the adjusters through their full range of motion to ensure they operate smoothly and without binding.
5. Troubleshooting
If you encounter issues with your Tusk Billet WP Fork Adjuster Knobs, consider the following:
- Difficulty Adjusting: If a knob is stiff or difficult to turn, ensure it is clean and free of debris. Do not force the adjustment; excessive force can damage the internal fork mechanism.
- Loose Knob: If a knob feels loose, re-check its installation to ensure it is properly seated and secured.
- No Change in Suspension Feel: If adjustments do not seem to affect suspension performance, verify that the knobs are correctly engaging the internal adjustment mechanism. If the issue persists, consult a suspension specialist.
