no pro-max's here. Carbs are tunable just as your old 4bbl. Looking forward to getting some track time this year. I did jump up to 70's, went with the purple springs and I'll probably have to jump up a few on the squirters.



OK, so you are jetting up the center carb, which is the one you idle and cruise on. Why would you not want to have the same adjustability on the outboard carbs which are the the ones which will open on wide open passes? Trying to compensate for the outboard carbs with larger jets in the center carb will tend to lean out the front and rear cylinders, but still foul plugs around town.
