"According to Power News Magazine
(
http://www.mototuneusa.com/break_in_secrets.htm ), all engines should be run-in hard. Anyone from here done this or know of anyone who has done it this way? (I will say that I've heard to do it this way before but the source and exact details escape me.)"
I run in all of my motors this way, both new from the manufacturer and those motors I've assembled myself. This includes Subaru, Jeep, Harley Davidson, and BMW motorcycle motors.
In the past, before I knew better, I took the baby them just like the manufacturer says to approach. More often than not that resulted in high oil consumption, engine oil that dirtied quickly and way before scheduled changes, and generally lackluster performance.
You make your choices and take your chances.
