yea, you'll need to rejet. probably something around a 124 and possibly need to go a size larger on the fuel line. you have one vacuum line from the intake to the diaphram on top of the carb. The other line running from the valve cover to the stock cleaner is for crankcase pressure relief, just a vent tube. It's run into the stock air box to recirculate any oil mist. it need to freely flow air. tie it up out of the way so no water or trash gets into the valve cover.
