Thanks to all that responded to my original post. I finally got the drain plug loose. I used an impact driver ( set at very soft) and it came loose. I also did this when the unit was cool. I switched the filler plug and drain plugs around so that I could snug the drain plug. Does anyone know what the Suzuki part number is for the drain plug? I could also use the number for the filler plug as well. The only difference I see in the plugs is a magnet in the drain plug itself. There was very little gunk on the magnet when I drained the oil.
