k, Id like some opinions on a ballpark for my jetting. I have a 391cc rz passion 12port, with +4mm, makes 182psi @ sea level with milled head, boyeseen dual stage carbon pros, pods, 34mm mikuni tm flatslides, rockets. When I ran 30m carbs with the 385cc prior to rebuild a 370 main was lean, and I didnt get a chance to figure out what it was before getting these 34`s. Trying to guess a roundabout size on pilots and mains. was thinking 30/410ish?
