Ok so I'm soon making the change from t5 to Small bore cpi pipes. Just did some research on here and right now the way it sits with my dune port, .030 milled head, v3reeds and +4timing, CPI's are the way to go plus I'm going with coolhead 19 cc domes to get up to 180psi. What type of jetting changes am I looking at from going to cpi pipes and 19cc domes? Some post say you don't need to touch it. Some say just move the needle one position but didn't state up or down. I just want a good idea what I'm going to be changing. Right now with the milled head I'm at stock pilot with 330mains. Some people said to move the needle to the 4th position etc etc. I seen so many different things but they didn't seem to have the mods I have done already so that's why I need expert advice from a goorue. Thanks in advance
