Motorcycle Repair: true duo-carb. rejet, air fuel mixture, pet cock

Question
I have an 87 FLHS 1340 all stock.I want to put on true duo exhaust!Will I have to do any jetting to my stock carb?I am in the process of rebuilding the carb right now as it likes to drip a little if I leave the pet cock on for any amount of time.Am replacing the float too.Soon as UPS comes round.Thank You for your time!

Answer
You might get by without rejetting, but it depends on how much the exhaust flows. You will need to reset the air/fuel mixture screw. the best way to tell is get the bike running, ride for about 10 miles and check the plugs. If they are sooty, then you are to rich and needs rejetted. While and you are to lean.
Happy New Year
