Routine maintenance on a motorcycle typically begins with a regularly scheduled oil change. Harley-Davidson recommends that the oil and oil filter on a Road Glide motorcycle be changed every 5,000 miles. In the event of very hard, dusty riding or in very cold weather, consider changing the oil more frequently. The time to complete this task is approximately 30 to 45 minutes, depending upon skill level.
Step 1: Warm the motorcycle up to normal operating temperature. Turn off the engine after it is hot.
Step 2: Remove the oil filler plug on the right side of the bike.
Step 3: Place an oil drain pan or other suitable container under the motorcycle. Remove the oil drain plug located at the front left side of the oil pan with a socket wrench. Allow all of the oil to drain.
