i don't own a wr yet, and I have never jetted a bike. I can, however, tell your to browse the threads stuck at the top of this yamaha sub-area. all the info you will need is in there, and also check out thumperfaq.com -- i've been reading as much as I can for the last few days, and have learned a lot.

all the information you could possibly need is there, and done thoroughly. I doubt you will get any better info from the guys browsing this board, as this same question must have been asked 100x by now. there's even a jetting mod area where everyone has posted what they did to their bike, what elevation, etc. find it, it'll help. good luck!
