If I degoat my new Vulcan 750 and keep the stock pipes & mufflers. Will I have to rejet the carbs and if so to what size jets? Or will adjusting the fuel/air mixture screws to reduce backfiring be enough? Will degoating negatively affect performance? Will degoating make the stock exhaust to loud? What I'm looking for is a deep throaty rumble. Or, should I just leave well enough alone? Thanks.
