As you may know I don't spend a dime on shit I can make myself. Take for instance this baffle I machined from some spare aluminum tubing. I turned a step to make it appear to be floating in the pipe, and I added a screen for a little more back pressure. RRRRRRIPPPPPPPPPPP.
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
