I'm new to the '04 WR450 and all the mods. I've been sifting through so much jetting crap all over this site it's making me dizzy. With the basic (throttle stop, baffle removed, grey wire cut, airbox opened) where/how would I find out the right jetting and other setup/mod info that I need for the bike at 500ft alt. What about the YZ timing or any other mods? If someone has the time and could list the whole lot in one thread, it would make us newbie 'modder's' very happy. If a search is suggested could you list "Words to search for" to save time. Thanks to all you guys who help us out here all the time. Hopefully I'll be helping others out as soon as I've got this all figured out.
