I have a sportster and it doesn't have a drain plug. It has a drain hose that is located under the engine and is connected to the rear pipe mount on a stud with a small hose clamp. Loosen the hose clamp and just pull the hose off the stud and the oil will drain. Don't forget when replacing the oil to put about 4 oz into the filter before putting it on and make sure the oil starts to come out of the drain hose before reconnecting it to the stud or the oil will get vacumed similar to vapor lock. Hope this helps.
