Here are a couple of photos confirming what others have said. The first photo shows the standard setup "disassembled". Showing the microphone with the small fin (faces outwards, away from mouth), the plastic clip (that is the official way to do what you have done with your piece of tape) and the windsock. The second photo shows the plastic wind clip installed.
Having said all that, I have this set up and my wife and I have 2 (identical) full face helmets and we also have the issue you describe. From the front seat, I don't have much wind noise at all, people I talk to on the phone tell me that there is no (or negligible) wind noise. When I try to talk to my wife, I get a lot of wind noise in my headset as soon as I switch intercom. I have tired both the boom and non-boom miss (since we have full face helmets), and both setups had the same issue. The noise is worse at higher speeds.
I have never found a solution, so would love to hear from you if you ever find a fix.
