Unlike most vehicles, the Harley Sportster Evolution Engine has an oil drain tube, not a plug.

This tube is attached by a house clamp to a nipple welded to the frame.

Loosen the house clamp with a Flathead Screwdriver. Do not remove the tube until you have your drain pan in position.

Removing the cap/dipstick from your oil tank at this point may help your oil drain faster.

Pull the hose free from it's nipple and allow the oil to drain into your drain pan.

When the oil slows to a drip, replace the hose. Do not tighten the clamp yet, we will return for that later.
