- Install Footpegs and Levers: Mount the footpegs, brake pedal, and shift lever onto the rearset base plates.
- Connect Shift Linkage: Attach the customized shift linkage. Adjust its length to achieve the desired shift lever position.
- Connect Brake System: Reconnect the rear brake master cylinder to the new brake pedal. Ensure the external return spring is correctly installed. Adjust the brake pedal position and verify brake light activation.

3. Operating Instructions
Once installed, the Arashi Adjustable Rearsets allow for fine-tuning of your riding position.
3.1 Adjusting Footpeg Position
The rearsets offer multiple adjustment points for the footpegs. To adjust:
- Loosen the retaining bolts that secure the footpeg to the base plate.
- Slide the footpeg to the desired position (forward, backward, up, or down, depending on the design).
- Once the desired position is achieved, securely tighten all retaining bolts. Ensure equal adjustment on both sides for balanced riding.
3.2 Adjusting Shift and Brake Levers
The shift and brake levers can also be adjusted for optimal ergonomics.
- Shift Lever: The length of the customized shift linkage can be altered to change the angle and height of the shift lever. Loosen the lock nuts on the linkage rod, rotate the rod to adjust length, then re-tighten the lock nuts.
- Brake Pedal: The height and angle of the brake pedal can be adjusted. This typically involves loosening a bolt on the pedal pivot or adjusting the master cylinder pushrod. Ensure the brake light activates correctly after adjustment and that there is no drag on the brake.
Always perform adjustments while the motorcycle is stationary and stable. Test the functionality of all controls at a low speed in a safe environment before riding normally.
4. Maintenance
Regular maintenance ensures the longevity and safe operation of your Arashi Adjustable Rearsets.
- Inspection: Periodically inspect all components for signs of wear, damage, or looseness. Pay close attention to bolts, pivots, and the footpeg knurling.
- Cleaning: Clean the rearsets regularly with a mild detergent and water. Avoid harsh chemicals that may damage the anodized finish.
- Lubrication: Apply a small amount of appropriate grease or lubricant to pivot points (e.g., shift and brake lever pivots, ball bearings) to ensure smooth operation and prevent corrosion.
- Fastener Check: Regularly check and re-torque all mounting bolts and adjustment fasteners to their specified values. Vibrations from riding can cause fasteners to loosen over time.
5. Troubleshooting
This section addresses common issues you might encounter with your Arashi Adjustable Rearsets.
- Loose Components: If any part feels loose, immediately stop riding and inspect all fasteners. Tighten any loose bolts to the correct torque specification.
- Difficulty Shifting: Check the shift linkage for proper adjustment and ensure it moves freely without binding. Lubricate pivot points if necessary. Verify the shift selector is not obstructed.
- Brake Pedal Issues: If the brake pedal feels spongy or too stiff, check the brake fluid level and bleed the brake system if air is present. Ensure the external return spring is correctly installed and functioning. Verify the brake light switch is properly adjusted.
- Unusual Noises: Any new or unusual noises from the rearset area should be investigated immediately. This could indicate a loose component or wear.
If you are unable to resolve an issue, contact Arashi customer support or consult a professional motorcycle mechanic.
