I need to drain the oil out and change it. I found the drain plug down below the fill plug, but I can't get an allen wrench in with any kind of angle to turn it. Is there a special tool or am I going to have to loosen the motor mounts and lift the tail end of the motor. My other option is to slip a small soft plastic tube in the fill area and suction it out with my break bleeder, this option doesn't allow me to know if the case is toataly empty. Anyone have advise. Thanks
