bookieboy is correct, if you experience problems, it is because the engine was not built correctly. There should never be metal to metal bearing contact so there is nothing to "completely mate". A hard break-in would expose the problem right away while a gentle break-in may allow you to get hundreds, maybe even thousands of miles out of the engine, but, it will still suffer an early death.

"In my experience", which is all I can speak from, I've seen more than a few four stroke motors lock cams in cam bearings and snap chains because the new owner whipped the snot out of a new motor and the "hot spots" seized up before they could completely mate surfaces.
To each their own............
