Sporster oil change question
I've been watching several videos. I just want to be clear on this. The hose that is supposed to be hanging down and clamped onto the frame nipple is coming directly from the oil tank. So when changing the oil you are draining the oil tank not the motor itself like you would on a car? Is that correct?

Excellent, Thanks! I just found the hose.That nipple that the drain hose clamps on the bottom of the bike is located on my bike as part of the battery holder. Yep. Took the seat off and followed down to the battery holder. None of the videos showed that and it looks definitely factory to me. Not a mod. Thanks again

My 1991 is the same, easiest oil change you'll ever do. Pop the hose off the stopper below the battery, drain the oil. Refill and change out your filter, add some oil to filter (and rubber O ring) to speed fast refilling of oiling system. So much easier than all the later Sportsters!!!

Lots of youtube videos are done on 2013 or older bikes. Not many folk look to keep stuff updated. On 2014 and newer the pipe was modified I suspect to allow for the carbon cannister to mounted underneath.
It is a quandary with a dry sump bike that after it has stood for a while oil will will drain down. Then it requires the engine to be run to get the oil back in the oil tank.
Be aware that around 0.5 to 0.6 quart will not drain out so although a dry engine requires 3.5 quarts at the oil change it should require 2.8 quarts to fill the tank. But follow the FSM for the correct procedure of only putting in 2. Run the engine and check for leaks and then top up as required.
For completeness once the oil is drained change the oil filter. Put 4 oz of oil in the filter before fitting. Smear oil on the rubber seal before fitting. All of this is in the FSM.

Proceed. Definitely not a process to overthink. You have it all summarized here in the wisdom of those in this thread. An official service manual is a wise investment.
