I would try the 117 jet. That worked best in our blue buggy when going from a 114 main with a uni filter ported head and stock pipe. I used the vent line from the valve cover to the oil separator box on the old stock air box and put a vacuum fitting into the rubber intake boot. I didn't like the idea of crank case fumes venting from the line and thought that by putting it in the intake it might decrease some of the positive crank case fumes.
