My 04 takes right at 2 quarts to fill, including filter change. My 08 uses 2.5 with filter. Go figure... Just about everybody with an "L" has a different amount they add to full. I think you already know this but it's best to check a few minutes after shutdown. There is a valve in the bottom of the frame tank that on some bikes...and it's happened a few times with my 04...the oil will bleed out of the tank and into the bottom of the engine over night so it shows NO oil on the stick in the morning.
