On the instructions it says that for Race Conditions to use the Blue #3 position. I currently have installed the Blue #3, #45 pilot, #178 main. It runs best around my house at this but I will be riding at @1000' higher altitude this weekend and was wondering what the best way to lean it would be. Does anyone know if the Blue needle in third clip is a leaner/richer setting than the red needle 4th position? Is there a certain clip position on the Red/Blue needles that correlate? Example: Red #4 almost equals Blue #3.
