I've been meaning to install an oil cooler on my whip and I finally made some time this week to make the rear fitting. Parts bought include a left side oil cooler from a BMW r12 or something like that, an 18mm banjo-fitting from a Lexus turbo intercooler and some AN-6 fittings to connect to some 3/8 braided hose and I'm in biznass.
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
