How-to change the oil on a 2002 harley-davidson dyna super glide?

To change the oil on a 2002 Harley-Davidson Dyna Super Glide, start by warming up the engine slightly to thin the oil for easier drainage, then secure the bike on a stable surface. Place an oil catch pan under the oil pan, remove the drain plug, and let the old oil fully drain. Replace the drain plug, then remove the old oil filter using an oil filter wrench, lubricate the rubber gasket on the new filter with fresh oil, and install it. Finally, refill the engine with the recommended oil type through the oil filler cap, checking the level with the dipstick, and run the engine briefly to circulate the new oil.
