At this point "break-in" time and requirements aren't what they used to be (according to my race-engine builder friend), but load is still a good idea. Revs don't accomplish it.
He also recommends a quick 1st oil change.

I'll change the oil at 50 miles, then five hundred for a couple times. I won't be following the book verbatim, but no crazy stuff. I've always broken in like I ride them. Hard but not abused.
My dad always followed the book, his brother ran the engine for all it had. Growing up my uncles dirt bikes was always a little faster. Even with the rider swapped, over the course of four different sets of bikes.
Due to oil being below the site glass I drained it as soon as I got home to see how low it was, with 1.1 miles it was already sliver colored.
