'03 WR 450F owners, I know from reading the posts here that there is far more years of experience on this board than I have with bikes. Which of the above needles would you guys try first? The YZ needle (NDJN), or the *Non-USA needle(OBDUQ, see page 7-8 manual) . What performance gains should I expect from either?
Await your responses!

Good question. I have been pondering the same.

if you do all the YZ mods to your WR, yes, use the YZ needle.

Does the 450 have an AIR CUT valve like all other WR model years?

I run the NDJN needle and it works great on my bike.
