We had the same problem and found out that the oil plug isn´t on the bottom at all. It is on the left side, even with the top of the kickstand and just to the right of the kickstand. It has a phillip´s head screw in the middle of the plug and/or you can use a wrench to take the plug out. The plug is on the side, so be sure your drain pan is large enough to catch the oil as it shoots out a bit, up to six inches. If you need a picture from the manual I can email you one.
