In removing the carb for some cleaning and inspection, I noted its previous owner had installed the following: 160 main, 48 pilot and R1173L needle, set at the 2nd clip position. This may explain the slightly "rich" characteristics in engine perfomance and excessive smoking. OH, BTW, the engine has air box lid removed, after market air cleaner and PC Rev pipe and S/A. I am thinking of simply going across the board with those base jetting recommendations for 200's that feature Stage II tuning mods: 155 main, 45 pilot and R1174K needle. Or should I adhere to the adage where one shouldn't make more then one jetting component change at a time?
