Harley-Davidson Road Glide 105th Anniversary Edition 2008 Owner's Manual

Regular maintenance includes oil and filter changes every 2,500 to 5,000 miles, checking tire pressure and tread regularly, inspecting brake pads and replacing them if necessary, and ensuring all lights are functioning. Additionally, check and maintain proper belt tension, and lubricate moving parts as specified in the owner's manual.

To improve fuel efficiency, ensure your tires are properly inflated, perform regular maintenance, use high-quality fuel, and avoid aggressive acceleration and braking. Additionally, consider upgrading to a high-performance air filter and exhaust system to enhance engine efficiency.

First, check the battery connections and ensure the battery is charged. Inspect the fuses and replace any that are blown. Verify that the kill switch is in the correct position and that the fuel valve is open. If these steps don't work, consult a professional mechanic or refer to the service manual for further troubleshooting.

To adjust the suspension, refer to the owner's manual for the specific adjustment points. Typically, you can adjust the rear shock preload using a spanner wrench to suit your riding style and load. It's important to make adjustments incrementally and test ride to ensure optimal comfort and handling.

Common issues include electrical problems, such as faulty wiring or blown fuses, which can be resolved by inspecting and replacing affected components. Another issue is excessive vibration, which may be mitigated by checking engine mounts and ensuring all bolts are tightened to specification. Regularly inspect and maintain the drive belt to prevent slippage or breakage.

To upgrade the audio system, consider replacing the stock speakers with high-quality aftermarket options and adding an amplifier for better sound clarity and volume. You may also want to install a Bluetooth-enabled head unit for modern connectivity. Ensure all components are weatherproof to withstand riding conditions.

The recommended tire pressure is typically 36 psi for the front tire and 40 psi for the rear tire. However, it's important to refer to the owner's manual or the tire manufacturer's specifications for the most accurate information. Check tire pressure regularly when the tires are cold.

To maintain the paint, wash the motorcycle using a gentle automotive soap and soft cloth or sponge. Rinse thoroughly and dry with a soft towel to prevent water spots. Apply a quality wax or paint sealant to protect the finish. Avoid abrasive materials that could scratch the paint.

Harley-Davidson recommends using SAE 20W-50 oil for most riding conditions. Ensure the oil meets API standards and is specifically designed for V-twin engines. Regularly check the oil level and replace it according to the maintenance schedule specified in the owner's manual.

To enhance comfort on long rides, consider upgrading to a more cushioned seat and adding backrests for both the rider and passenger. Install handlebar risers to adjust the riding position, and consider highway pegs to allow for varied foot placement. Ensure your suspension is properly adjusted for maximum comfort.
