I previously posted some pics of the rotor carrier I turned and mated to a star hub. It wasn't easy but now looking at the final product (minus polish) I think it was well worth it. I made a custom axle, the "wishbone" caliper bracket and all needed spacers and tie rod. This is going on a my bud Pedro's wishbone frame shovel. The springer is Acme and I must say they kick ass with their quality and design. I can't wait to see his bike finished up.
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
