Where is Oil drain plug location on a 2007 harley-davidson sportster 883?

The oil drain plug runs out of your oil tank and down through the casing that houses your transmission, it is located in the middle of the casing, in between the frame rails. It has a black plastic plug in the goodyear rubber hose. You will need a flat tipped screwdriver to loosen the clamp that holds the plug in. It is pretty much in line with your kick stand if you have your bike leaning on it.
