Yesterday afternoon I changed the oil and filter. It has 750 miles and this is the 3rd oil change. When I began to reinstall the new filter I was not sure about where the spring went so I checked the manual. It also shows a flat washer that goes on before the spring, but I don't have a washer. I either lost it when I changed it before or it didn't have one. Not sure where it would go if I had one. Has anyone else come up short of one. Maybe I need to pick one up? I also changed over to Rotella T synthetic. I had let the bike set for a couple of days without starting it and the dip stick was showing over full from the oil draining out of the torque converter. I changed it without starting it and lettting it warm up. It drained enough out that it took nearly 4 quarts to refill. This way, it didn't leave as much of the old oil in it. Should be close to being all synthetic. Haven't driven it yet but am curious if it does shift better as some have indicated.
