I posted this once a few weeks back, but the TT format changed and I cannot find the original post. Anyway, I had purchased the JD jet kit, but I am not sure what needle to go with. I live near raleigh, North Carolina and ride elevations from sea level to 2500 feet. It is hot here in the summer, so what needle do I go with. Should I start with the red or blue needle? Also, what clip position would you recommend? I have changed my MAJ and PAJ, do I need to change them back to stock? I also ride in Eastern Ohio and West Virginia, how much will this affect my performance changing temperature levels between here and there?
