Don't want to start anything with this link. I have not seen it here on RCU before but if it has passed around before then I haven't seen it and possible a few others have not seen it either. I have broken in my 2 stroke and 4 stroke snowmobiles and racebikes and dirtbikes with this method and have yet to have a problem. My motors burn no oil.
