Really up to you..every 'break-in" style will differ as will oil change intervals, parts, etc. Really the only thing that people can't bicker over is to keep the oil clean and use the best possible filter available. I will say the first 50-100 mile oil change is something I like to do on a new motor, I want to confirm she's up and running, but I also want the debris from the build and initial run out of the mill relatively quickly.
