After reading Dino comment, just only can say AMEN! Many people, including myself have broken in their engines in several forms and he picks what he makes more confidence.
Firstly I used the 4 stroking method at full throttle, but a comment from a metallurgic engineer friend of mine make me think about the way I broke-in mine engines. They lack of proper heat and metal needs to get tempered and the correct clearances.
Experimented with other break-in methods and lastly I readed the booklet that came with my own engines, found that engines to run properly needs to have their own operating temperature, tested the idling method and after going to the track very rich and found better results than in the past.
Everything in this hobby is a way of experimentation and evolution. What seems logical today, probably tomorrow is outdated or simply a nonsense. Like says the slogan of one good scotch whiskey: Keep walking.
