jestal, do you use (or have to use) a PCIII as well, with your setup?
Yes, I have a PCIII on it. I used the fuel map that Holeshot has available. It was developed with their pipe and their cans but I figured it would be pretty close for starters. I have modified the map some on my own so it is not the exact Holeshot map but the Holeshot map ran in the bike for several hundred miles before I meddled with it and it ran fine. I already had the PCIII on the system before I put the Holeshot header on so I don't know how it would have run without it.
