The recommended oil type for a 2008 Harley-Davidson Heritage Softail is SAE 20W50 synthetic motorcycle oil.
You should change the oil every 5,000 miles or once a year, whichever comes first, for optimal performance and longevity.
The recommended tire pressure is 36 psi for the front tire and 40 psi for the rear tire.
Check the battery connections and charge, inspect the ignition fuse, and ensure the starter relay is functioning. If problems persist, consider having the starter motor checked by a professional.
Ensure the air filter is clean, check for proper tire inflation, and verify that the fuel injectors are functioning correctly. Regular maintenance and throttle body cleaning can also improve fuel efficiency.
Regularly inspect the belt for signs of wear or damage, adjust the tension according to the service manual, and clean it with mild soap and water as needed.
Common issues include faulty connections and blown fuses. Check wiring connections, replace any blown fuses, and inspect the battery terminals for corrosion.
To adjust the suspension, use the pre-load adjuster located on the rear shock absorbers. Turning it clockwise increases pre-load for a firmer ride, while counterclockwise decreases it for a softer ride.
Inspect the brake fluid level and top it off if necessary. Check for air in the brake lines and bleed the brakes if needed. Examine brake pads and replace them if worn.
Regularly clean your bike with mild soap and water, dry it thoroughly, and apply a protective wax or polish. Store it in a dry environment and use a cover when not in use.
