Weather is warming up and my bike seems to be missing a little more lately. I installed a JD jet kit and went with there specs and it seemed to work fine in colder weather but now it has a little miss at a quarter throttle. I don't think its the normal WR stutter because it happens when when opening up the throttle slowly. As soon as i hit about quarter throttle the bike starts missing till I pass that throttle position. Elevation is sea level with a 48 pilot jet, 170 main jet, JD Red needle on the 5th clip position. Bike has a YZ header, Lexx MXE silencer and Hot Cams. I emailed JD jetting with the mods done to the bike and that is the jetting they told me to run. What should i do i'm thinking it may be the needle to rich because my license plate is a little sooty from the exhaust pipe.
