I just bought a new left over wr450 yesterday. I am new to posting here but not to reading and informing myself about my recent purchase on the wr. I credit my purchase to the info provided on this forum. Thanks for allowing me to sponge off you guys. I just want to make sure of the free mods to do on the '04. No AIS on the '04 right? Remove snorkel right? Add insert to exhaust (at least)? Remove gray wire right? JD jetting kit right? Throttle stop right? I have already looked at the jetting page. My question is that if you order from TT do you have to call and specify all the particulars or is it in a package. I think I remember reading that it comes with instructions also right? I am looking for the minimum and least costly mods at this time. Looking to get gift certificates for christmas.
