Aim for between the high and low lines. The difference is only about 300-500ml. If you get it a little above the high line it doesn't matter. I've also seen the oil take over a day to settle in a cold engine, so if you're incredibly anal about it then it'll take as much time away from you as you're willing to spend. Not me. I just ride it.
