I have modified my exhaust, will remove the smog pump (TT AIS removal kit). I am putting the shorter throttle stop screw in. What should I jet this bike for riding elevations 3,000-8,000 feet? I read a lot of threads about jetting and found many dealing with the YZF or the WR250, but not many about the WR450. From what I did read I found the following suggestions. Stock 170 main 42 pilot 70 leak Yamaha GYTR Kit 165 main 48 pilot 90 leak Any suggestions? If I buy the GYTR kit am I good to go? Any other suggestions?
