First know if they are air screw or fuel. Often plugged so the carbs have to be removed. Ideally you are only looking to be able to choose any rpm and the motor will stay there for road manners. Often with lean at idle the motor will not hold 1500~2k rpm and always hunt and stutter. Over rich and jetting kits will make it worse with modern fuels or imports from california.
