I have bolted 650 Eddy carbs to factory iron intakes before and they work fine. Your electric choke is easy to hook up and there are many diagrams and videos in the net for you to choose your best option.
The AVS 2 will work better than the factory carb because the annular boosters give better low end throttle response twocents
