Setup and Installation
Tools Required:
- Appropriate wrench or Allen key for handlebar mirror mounts (not included)
- Thread locker (optional, recommended for vibration resistance)
Installation Steps:
- Safety First: Ensure the motorcycle is stable and turned off before beginning installation.
- Remove Existing Mirror (if applicable): Carefully unbolt and remove the old left-hand mirror from the handlebar mount. Retain any washers or spacers if they are to be reused.
- Prepare New Mirror: Inspect the Arlen Ness mirror for any damage. Ensure all components are present.
- Mount the Mirror: Position the Arlen Ness mirror stem into the left handlebar mirror mount. Ensure the mirror is oriented correctly for the left side.
- Secure the Mirror: Hand-tighten the mounting bolt. If using thread locker, apply a small amount to the bolt threads before tightening.
- Adjust Position: Sit on the motorcycle and adjust the mirror to achieve optimal rearward visibility. Ensure the mirror head can be manually adjusted for fine-tuning.
- Final Tightening: Once the desired position is found, securely tighten the mounting bolt using the appropriate wrench or Allen key. Do not overtighten, as this can damage the threads or the mirror stem.
- Check Stability: Gently test the mirror's stability. It should remain firm and not vibrate excessively during operation.
Operation
The Arlen Ness Forged Oval Left Hand Mirror features a convex lens, which provides a wider field of view compared to flat mirrors. This wider view can help in identifying objects in your blind spots. However, objects in convex mirrors appear smaller and farther away than they actually are. Exercise caution and use direct observation when changing lanes or making turns.
The mirror head can be manually adjusted to fine-tune your viewing angle. Periodically check the mirror's adjustment to ensure it provides optimal rearward visibility for your riding position.
Maintenance
To ensure the longevity and appearance of your Arlen Ness mirror, follow these maintenance guidelines:
- Cleaning: Clean the mirror glass with a soft, lint-free cloth and a mild glass cleaner. Avoid abrasive cleaners or harsh chemicals that could damage the chrome finish or the mirror surface.
- Chrome Finish Care: The mirror features a durable chrome finish. To maintain its luster, regularly wipe it with a soft cloth. For deeper cleaning or to remove minor blemishes, use a chrome-specific polish or cleaner as directed by the product manufacturer.
- Fastener Check: Periodically check the mounting bolt for tightness. Vibrations from riding can cause fasteners to loosen over time. Tighten if necessary, but do not overtighten.
- Material: The mirror is constructed from stainless steel, offering good corrosion resistance. However, exposure to harsh elements or road salts can still affect its appearance. Rinse with fresh water after riding in such conditions.
Troubleshooting
- Mirror Vibrates Excessively: Ensure the mounting bolt is securely tightened. Check for any loose components in the mirror assembly or handlebar mount.
- Poor Visibility: Re-adjust the mirror angle. Ensure the mirror surface is clean and free from obstructions. Remember the convex nature of the lens makes objects appear farther away.
- Difficulty Adjusting Mirror Head: Check for any debris or corrosion in the swivel mechanism. A small amount of silicone lubricant may help, but avoid spraying directly onto the mirror glass.
