I did the throttle stop mod with the YZ throttle stop. It had red loctite on it already & I used a little motor oil on the end so it won't corrode. Actually a guy from Thumpertalk mailed me the YZ throttle stop - YZ needle & YZ pilot jet for free over a year ago. I forgot the guys name but thanks a bunch! It was tougher than I thought it was going to be. The hard part is getting to the throttle stop. I had to take the entire exhaust system off & it made it a lot easier to get to. What a difference it made. It sings now with hanfuls of throttle. I will do the Grey Wire Free Mod tommorrow.
