If you can turn the plug out, you can go to a large size plug. If you can't get the plug to come out, take the outer primary cover off allowing the oil to drain out as you remove the outer cover. Sure it's messy but you've got no choice. Now with the cover off, push down on the plug while trying to turn it out. It'll probably come out doing this. Then measure it and get the next size bigger. Tap the hole to the bigger size and install new plug. Good Luck!

    Now I don't know exactly which drain plug is in your bike now, I'm guessing a 1/2 X 20 thread. If so, go to Harley Part numbers 720, 706A, or 722. All are Harley parts and are plugs that have a 5/8" X 18 thread. Of course, you'll need a drill and tap for the hole. Usually the correct size tap is listed right on the tap. If not, consult a drill/tap sizing chart. Good Luck!

Looking for the oil drain plug and the transmission drain plug on a 2001 Harley Davidson XL 1200 Custom

Usually the oil drain is one the left side of the bike somewhere below the battery. Look for a hose that has a plug in it or one that connects to the frame. Harley had moved this drain so many times in the past that it's difficult to keep up with where the oil drain is located. The transmission and primary share the same oil. To drain it, find the drain plug on the bottom of the primary just below the clutch. Pour the new oil in the primary chain inspection hole of the primary.

Good Luck

How do I change the oil on a 2002 fat boy? Where is the drain plugs?

On the fatboy, the oil drain plug should be on the right side, just under the frame, directly below the oil tank. The primary drain is on the left side under the derby cover on the bottom. The tranny drain is on the bottom towards the rear pretty much centered.
And, as our darlin' little miss piglet said, a maual is worth the investment.
