Hello, I recently purchased my first Harley (05 Deluxe) and wanted to change the oil before I started riding. Unfortunately, I did not realize that there were 2 drain plugs at the bottom of the bike (one for the oil which in under the oil pan, but I drained another plug that's also at the bottom but closer towards the front and on the right side). I realized I was draining the wrong hole because not a whole lot of oil drained and the pan was still full. Does anyone know what that drain plug is for? and how do I replace the little bit that did drain out by mistake? I appreciate anyones help on this. Thanks in advance.
