Harley-Davidson Dyna Low Rider 2005 Owner's Manual

The recommended oil type is SAE 20W50 synthetic motorcycle oil, specifically designed for V-Twin engines.
It is advisable to change the oil every 2,500 to 3,000 miles or every 6 months, whichever comes first.
The recommended tire pressure is 36 psi for the front tire and 40 psi for the rear tire.
Start by checking the battery for charge and connections, inspect the starter relay, and ensure the fuel system is working properly.
Check fluid levels, tire pressure, brake function, lights, and ensure no loose bolts or fasteners.
To adjust the rear suspension, use the preload adjustment collar on the shock absorbers to set the desired ride height and comfort level.
The correct spark plug gap is 0.038 to 0.043 inches.
Remove the air cleaner cover, take out the old filter, replace it with a new one, and reinstall the cover.
Maintain proper tire pressure, perform regular maintenance, and avoid aggressive acceleration and braking.
Overheating can be caused by low oil levels, a faulty cooling system, or blocked air passages.
