I any one running a White Borthers R4 pipe with the Dynojet kit. I am curious what your settings are (main jet, mixture screw)? I have just bought the slip on and its on the way. I am running no airbox, clip is on the third notch (manufacture recommendation) with a 42 pilot no choke. I am also below 5,000 feet sea level. just trying to get an idea so I can have it pretty much ready when it gets here. Thanks....
