Hey guys, I have an 07 YZ450 and I am looking at buying a T-4 pipe from Procircuit. I called them and they recommend I run a 165 main, 42 pilot, NFPP needle in the 4 position from the top, and a 50 leak jet for this pipe. Does this sound correct? Right now I am running the 170/48 combo with everything else stock, and the bike runs great. I want more power from the pipe, but I don't want to mess up how well my bike runs from going to completely different jetting. My riding conditions are as follows: Lucerne valley, CA About 3000 above sea level A lot of wide open throttle riding. Any advice would be great appreciated. Thanks!
