The recommended oil type for the 2005 Harley-Davidson Fat Boy is SAE 20W50 motorcycle oil, preferably Harley-Davidson's own brand for optimal performance.
The air filter should be inspected every 5,000 miles and replaced every 10,000 miles, or more frequently if you ride in dusty conditions.
The recommended tire pressure for the 2005 Fat Boy is 36 psi for the front tire and 40 psi for the rear tire.
Check the battery connections for corrosion, ensure the fuel valve is open, verify the kill switch is in the 'run' position, and inspect the spark plugs for wear or fouling.
At 15,000 miles, perform an oil change, replace the oil filter, inspect the brake pads and fluid, adjust the clutch and throttle cables, and check the drive belt for wear.
The rear suspension can be adjusted using the preload settings. Use a spanner wrench to adjust the shock absorbers to your preferred stiffness, following the owner's manual guidelines.
Ensure the cooling fins are clean and unobstructed, check the oil level, inspect the exhaust system for blockages, and consider using a synthetic oil that can handle higher temperatures.
Maintain proper tire pressure, perform regular maintenance, use high-quality fuel, and avoid aggressive riding to improve fuel efficiency.
Common electrical issues include battery drain, faulty starter relays, and corroded connections. Regularly inspect the wiring and keep connections clean to prevent these issues.
Use a non-abrasive chrome cleaner and a soft cloth to clean chrome parts. Apply a chrome polish to protect the finish and prevent rust. Regular cleaning will maintain the shine.
