Hey what's up guys I lined up with a 400ex with a 416 kit and white brothers exhaust
We went from a roll in 2nd I had him till 5th and then he slowly pulled me on top. He said that he bike ain't running as strong and needs a rebuild idk but I had him by at least 2 bikes length. Now I just ordered my full exhaust and next week going get the fuel controller
