Bike is an 05 WR450 with all free mods done, 168 main, 48 pilot, Quickshot and DR. D pipe. Just installed adj. fuel screw and want to know how you set it correctly. I hear about holding the revs up and adjusting for the best sound and a couple other ways, how do you guys do it? My other question is I just received my JD kit and was wondering if I should use the setup they give or if you have found otherwise. I mostly ride at sea level and not during very hot times. I really only want to do this once as I dont have the time or inclination to be changing needles and jets all the time. I guess what I am asking is there a happy medium I can go with. Thanks.
