What codes can I put in my JD jetting guide to approximate the new needles so I can adjust my needle & jets accordingly as temps change. Also what would be the approximate temp change (20 deg or more?) to switch between blue and red needles or just go by how the bike is running. I'm going to start my kit with the JD blue #4, 165MJ and 42PJ. I figure it will be pretty close to my old settings of ELN #3, 168 MJ, 45 PJ (seemed slightly rich) which I changed from this summer to what is in my sig. Can't wait to tear into the carb again and get back out for a ride, haven't had a chance in the last 6 weeks!
