Demon carbs

I like and run them. Larger fuel bowls and see thru windows. I've drilled and tapped passages for fine tuning. Out of the box my 650 DP ran rich at highway cruise RPM with a wide band. I had to drop 2 jet sizes on the PMJ, opened the PVCR from .059 to .063, and decreased the MAB from .041 to .028 to cleanup highway cruise.
