If I remember correctly, you do three heat cycles of bringing the engine up to normal operating temperature at medium load for 15 to 20 min then let it cool completely. I thought it had something to do with annealing / reducing internal stresses in new engine components.
Although that is directly opposite of what I have been told by engine builders for break in of 2 stroke engines with plated cylinders that have the correct build clearances. Warm it up and ride it like you stole it because you need heat and engine loading to properly break in the rings.
