As you are actually kicking, you should not twist the throttle open, and THAT is what the manual says. But if you don't prime it with the accelerator pump, you're going to get a lot more exercise than you planned on. None of them that are set up correctly start any differently than that.
My bike will start with two easy kicks to get to top dead center, then an aggressive kick nearly every time. My experience with starting four strokes has always shown those who touch the throttle end up kicking the bike more and more often.
