I just finished my jetting woes, and finally got it right. I think. I've got the same carb your bike does and I don't thing the Canadian versions use anything different there. I ride at elevations over 4500ft and at temps less than 55 degrees in the winter. I was "Guaranteed" (by one of the self proclaimed jetting experts here) that using a 168 main, 200 main air jet, 45 pilot, 75 pilot air jet, and a 55 starter jet would work perfectly with the OBEKN needle. Turns out that that was too rich, eventhough it was leaner then what I started with using the stock OBDRS needle. I installed a 42 pilot and a 165s main and it turned out perfectly. Got a good test on this too and it is running great.
If you rejet with YZ specs, make sure you use an "E" type needle and not the "D" types spec'd for the WR. Good luck and once it's right you'll know it.
