Flathead here.
Here are some pictures of how to make use of limited space. The filter housing was made with lost foam method.

Where did you find the black housing between the carb and air filter?

The housing was built by me. I needed to put the oem carb in space indicated by fist in picture. I wanted a filter also. I took some flower arrangement foam and shaped the part. You have to get all the details in your foam part right before you fiberglass it. After glassing it & allowing to dry, pour gas through it & the foam runs out. TADA! You have a part.
This sounds easy but the reality is that in tight spaces such as this you will have a few failed attempts.
The reason it looks the way it does with filter on end is the carb needs a measured volume of air to operate the diaphram & needle. Usually the filter is behind carb with box wrapped around it & a small intake hole located on box somewhere. I just changed the set up to have the measured volume behind carb with filter on small intake hole. Same outcome just different arrangement. The volume of air & intake hole size are important. The folks that just add pods to oem cv carbs are often taken for a tuning nightmare of a ride without an end. If you are going to change a filter set up on oem cv carbs you have to be a thinker to get it right. The carb has 130 main & 30 secondary with oem idle jet. No stall or lulls at any throttle position, just hard pull through gears.

The mono shock is not stock. This was part of a cafe racer project, if I remember right.
