How do you change the oil on a 1997 Harley?

To change the oil on a 1997 Harley, start by warming up the engine slightly to thin the oil, then turn it off and let it cool for a few minutes. Place an oil drain pan under the bike, remove the oil drain plug, and let the old oil drain completely. Replace the drain plug, then remove and replace the oil filter using an oil filter wrench. Finally, refill the engine with new oil through the oil fill cap, ensuring you use the correct type and amount specified in the owner's manual.
