Well there is actually to parts to the answer your looking for. You are right it is not engine oil, but transmission oil. What is leaking is the drain plug to remove your transmission oil. There should be a check screw on the left side of your case to make sure that the tranmission is topped off. I like to change it after about 3 rides or 5 to ten hours....
