You do NOT want to run rich when breaking in a new motor, do you want the rings to gum up??

It's the same as when assembling a top end on a 2-stroke... Do not soak the piston and rings in oil, it gets enough from the gas/oil mix. It's the same as when a bike sits for a while, you don't pour oil in the cyclinder it gets lubed from the gas/oil.
