Folks...wondering if anyone can help with a jetting question. '02 WR 426, just installed JD Jet Kit (170 main, blue needle on 3rd clip, 42 pilot). First...I am getting a very distinct miss at 1/8th throttle that clears up just past 1/8. This was not a problem prior to JD kit. Also, I am getting no response from the Fuel Mixture Screw. Minor mods: exhaust Hot Cam, 'normal' WR mods. Any thoughts?
