Well I did!! Here's a sporty tokico radial mounted caliper for a NG sporty front end. These calipers are a dime a dozen on egay and stop on a dime. The adapter bracket I made from 2024 aluminum and matches the lines of the caliper nicely.
I make these to fit your original CV, or S&S Super E/G, Super B, Bendix, Mikuni and SU carbs. They measure 5 1/4 diameter x 3/1/8 total height and includes a 5" custom-sized K&N for your filtering pleasure. Mikuni & SU requires adapter bracket ($40). Please specify which style you want when ordering. See store for ordering info, or hit me up at firstname.lastname@example.org
