hey all, ao i just got a 03 wr450 in july. figured i would ride it the way it was for a while before i would start do any mods to it. i am slowly finding out that there have been things already do to. this i am not complaining about just a little disappointed because i figured i was going to be able to do all the free mods to wake the bike up a little. first thing i noticed was the PMB insert. which it doesnt run lean so it must be jetted for the open exhaust. then today i went to go do the grey wire mod only to find out it had already been done. not sure about the ais removal. but non-the-less i rode my buddys yz250f and it seemed to have just as much nut as my bike did. so im curious, whats next as far as getting some more nut out of it.
