Get some zinc additive to add to the (non-synthetic) oil, the oil this day and age don't have enough.  Before you start it, tip it which ever way to let oil run down the cylinder walls and to the valves.  Get it fired up and keep it off idle varying rpm till it's warmed up...while driving. Once it's warmed up start getting on it harder and harder, just like hitting the straights and letting off some through the corners.  Letting off lets it pull oil up to the rings better so it'll flush things out some. After say a half hour of that drop the oil while hot. It'll pry look like metallic paint.  Fill it back up with oil and additive and run it again, drain again and make sure there aren't any bad things in the oil.  I'd continue the conventional oil for the first race or two to help get the rings sealed along with the additive.  After that pick an oil and stay with it.  I've had good luck with Coolpower Green Medium in my ohv....your results may vary.

Start it up, make sure it runs well.

Take it to the race track, race.

Change oil after the race.

Two races on regular oil, switch to synthetic.

That's all I've ever done to break in any of mine.
