    What is the actual measured pop-off pressure on each Carb? Those A/M Mikuni SBNs normally come with 115gr Springs. HSI could have forgotten to swap or installed wrong Spring? You could insert a Jet (try a #60) in the Return Line to raise the Fuel Pressure going into the Carbs so that the Needle...
