I'm currently running a CB750F DOHC with CV Kiehlin carbs and pods, 4 in to 1 pipe with no baffles. I have yet to jet them or do anything but thourough cleaning in Pinesol, reassemble and ride, yes I have some after burn/popping when I'm decellerating but other than that all is well. I found the CV easier to teardown and clean than say the early Kiehlin with the rocker shaft controlling the slides.
