Ok so i have searched and searched all over and i haven't really got an answer to this question. What are all the carb jetting for 34mm carbs on a 96 xlt 600 with PSI triple pipes. I have contacted PSI and they said 3 main jet sizes but some people say 2 jet sizes. So there is no need to change the needles down or up? I just want the best setup for these PSI pipes. Also i would like to have my plugs brown. Now they are black.
