Harley-Davidson Road King Custom 2006 Owner's Manual

To change the oil, warm up the engine, place the bike on a level surface, and remove the oil drain plug. Allow the oil to drain completely, replace the drain plug, and fill the engine with the recommended oil using the dipstick to check the level.
It's recommended to use a high-quality 20W-50 motorcycle oil that meets or exceeds the specifications outlined in your owner's manual.
Start by checking the battery voltage and connections. Ensure the fuel is fresh and the fuel valve is open. Inspect the spark plugs for wear or fouling and check the starter motor and solenoid for functionality.
Regular maintenance includes oil changes every 5,000 miles, air filter inspection every 10,000 miles, and brake fluid replacement every two years. Regularly inspect tires, brakes, and drive belt for wear.
Loosen the clutch cable adjuster, remove the primary cover, and adjust the clutch pushrod to have minimal free play. Re-tighten the cable adjuster to achieve the desired lever free play.
The recommended tire pressure is typically 36 psi for the front tire and 40 psi for the rear tire. Check the owner's manual for specifics and adjust based on load and riding conditions.
Remove the caliper, take out the old pads, compress the caliper piston, and install new pads. Reattach the caliper and ensure the brakes are functioning correctly before riding.
If overheating occurs, check the coolant level if applicable, ensure the oil level is correct, and verify the cooling fans are operational. Avoid idling for long periods in hot weather.
Performance upgrades can include installing a high-flow air filter, performance exhaust systems, and re-mapping the fuel system. Consult with a professional for optimal results and compatibility.
Common issues include battery failures, faulty connections, and blown fuses. Ensure all connections are clean and secure, check the battery condition, and replace any blown fuses.
