I did the method CJ showed you. I do not know how true the article is or if the photos they showed is really from their break in... but I bought it. Ran the hell out of it then changed the oil at 2 hours. It runs fine for me no problems. The article made alot of scence so I did it that way.

I broke mine in the mototune way. I have bought a lot of new quads and broken them in several ways. I seem to consistently get better power out of my quads by breaking them in the mototune way.
