I recently picked up a 08 WR450 from OTD Auburn and I got the GYTR Power-up kit & the promoto billet exhaust tip. I installed all the new jets and needle, adjustable air/fuel etc. disconnected the grey wire the whole enchilada. I am still working through tweeking it in for my area and am considering moving from the 4 posision on the needle to the 3rd, I am also considering a smaller main jet. The issues I'm having are 1 my milage sucks, I realize there has to be some sacrifice for the extra HP but I'm talking like 50-60 mi./tank(stock). I put a 3.6gal tank on and got about 100 mi. last weekend but I still would like to get out a little farther. It also seems a little ruff when I level off on the throttle.

The XR is a slower reving motor were the WR is a snap short strock motor.

I found that my XR650r got what my WR450 got when doing the same rides back to back
