Pat, I still haven't tried my Truxton needles only becasue I want to dyno with stock and my current set up. Sounds like I do have to get away from the stock ones at some point. I do have a question though. What is your seat of the pants set up with the Truxtons? We run different pipes and I do have cams but it may give me a good start point. I was thinking leaving the pilots at 42 and trying 130 to 140 main jets.
