I'd break it hard.Run it like its stolen.With modern metalurgy you really don't need the baby break in. Vary the load, do a lot of different cycles up and down through the rev range. Often people baby the motors and the rings don't seat.
The last two new machines I had were broken in this way and used zilch oil and when sold at super high miles were still running strong.
Before the rebuild did they do a leakdown test?
