I changed the oil on my 02 1150gs (on the centerstand) and let it drain completely. changed the filter, then refilled with about 3.5 qts of 20/50 now Ive test ridden it and let it sit on the side stand for several minutes, then on the centerstand for 20 + minutes and the oil level is showing just below the top red line in the sight window. I was told to put in just under 4qts ....Im glad I stopped short of that. is the level too high at this point? I was shooting for middle of the sight glass.
