So you want a simple cafe racer or road thumper without spending too much dough? Check out these guys, RYCA Motors who are building some cool customs from a rather overlooked yet readily available motorcycle, the Suzuki Savage 650cc aircooled single. I really love the tank.
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 email@example.com
