It is recommended to change the oil every 5,000 miles or once a year, whichever comes first.
For the 2008 Softail Deluxe, the front tire should be 36 PSI and the rear tire should be 40 PSI.
Check the battery connections, ensure the fuel valve is open, and verify the kill switch is in the 'run' position. If issues persist, inspect the spark plugs and fuel system.
At 10,000 miles, perform an oil and filter change, inspect the brake pads and rotors, check the belt tension, and lubricate all necessary parts.
Use a spanner wrench to turn the adjuster cam on the rear shocks to achieve your desired preload setting. Consult the owner's manual for specific adjustment instructions.
The fuel tank capacity is approximately 5 gallons (18.9 liters).
Press and hold the trip button on the speedometer until the display resets to zero.
Stop the motorcycle in a safe area, turn off the engine, and allow it to cool down. Check coolant levels if applicable and inspect for any leaks. Seek professional help if necessary.
Inspect and adjust the drive belt tension every 2,500 miles to ensure proper performance and longevity.
