I just got my '05 wr 450 and I could not beleive how restricted it was. I have to say I was fairly disappointed on the first ride. I just sold my '01 xr650r (plated) that was all opened up. I immediatley came home and did a search online for wr450 mods. Thumpetalk came up and I've been glued ever since. I put in the short throttle screw, took out the air box snorkle, bought and put on white bros. e2 silencer. Now, what should I do next? I am thinking it will be running pretty lean now, so jetting would be my guess. I am not extremely familiar with rejetting, as I have never done it myself(although i've witnessed). I do think I could handle it though. I need suggestions on what jets to change, clip positions, etc..I was hoping not to buy a full jetting kit just yet. I live at 1200' elevation and ride between sealevel and 5000'. Weather is generally dry and warm (65-90 degrees). Any sugestions? ...also, yamaha salesman said '05 wr450 have 2 gray wires and was not convinced that disconecting them made any difference. (?) ...cut or don't cut? Has anyone done this mod on an '05 wr450? ...lastly, how do I get my hands on Lowedog's ais removal kit? Thanx in advance for the help!
