Alternate Break in of a 4-stroke engine

It's hard to compare either theory since most of us don't have two sleds to break in both different ways under the same operating conditions. To say that your sled doesn't use a drop of oil because you broke it in either the Yamaha way or the mototune usa way really doesn't prove a thing.
