It's a real bummer to lose all the info that was on here. I was just milling through the engine break-in stuff when we lost it all. Anyways I was wondering what everyone thinks about this topic. I remember reading to break-in with regular 2-stroke oil at 25:1, about 3 tanks of fuel. They thought that synthetic was too slick to let the parts wear together properly. Then after 3 tanks of fuel switch to a good synthetic at about 40:1. What does everyone think on this? Are these good #'s to go by? How many of you rode like a demon out of the box for break-in and who took it a little easier? My understanding is not to hold it wide open too long but use the full range of the engine to make sure everything sets up properly. I bought some Kendall GT-2 oil to start off.
