I just received my psi single pipe for my zr 900 (about time!). No carb/jetting specs came with it. I called them for a reference point. They informed me that they have not been able to get much time on the sled. They suggested to leave the air and fuel screws alone and no staggering of jets is needed. They said start at 490's and go from there, WHAT? I know people with the speedwerx single are at 450's and the D and D people are at 460's, but 490's? Give me some feed back. The people with the 460's , did you raise your needles at all? I have a power breather, cones removed, and carbon tech reeds and am at 750 ft sea level. I am thinking 460's, what do u think?

I ran the Black Tragic Racing NOT so super single and started with 460's clip in the 4th position and it was TO RICH. I dropped to 410's. same clip. 30 degrees @ 1300' if this helps. I have since removed the pipe as it LOST power on the bottom end and I am back to stock. V-force reeds will follow. Dan
