I just changed my rear end gear oil, and I want to make sure I did it right. The shop manual said to put it on the side stand on level ground, which I did. It just doesn't seem that when I re-filled it that it took much before it started leaking out the fill port (which indicates it is full.) I cracked the drain plug to make sure there was new oil in the gear area, and there was. Is there a possibility that it should be standing straight instead of leaning on the kickstand when you re-fill it? This would get a little more oil in the rear. The shop manual said to do it on the side stand, and I did. Just hope I did it right.
