Hi all, I am now the proud owner of an 05' wr450 and a wr250. I bought em the same day. (his n hers) I have been working on my bike the last couple days. I have done the grey wire,throttle stop,pipe cork, and rejetted. This thing rips, but I know there is more there. I have not changed the needle or removed AIS yet. What if I were to use a YZ needle and remove the AIS? Also I have followed the link on the 450 mods thread and it is dead, so how do I remove the AIS. I should probably mention that I am running at 7000 feet.
