• Any of the regular posters in this thread handy enough at fabricating, and keen enough, to have a bash at making a plenum that would enclose the trumpets of some ITB's, and connect to the stock airbox feed?

  • Ah, so ITBs are back on the table? I've made a custom airbox from GRP, but it was a bit rough and ready:

    The plastic bit bolted to the ITBS is the part of the standard Yamaha airbox, the rough looking black bits are the parts of the airbox I made myself. There's an ITG panel filter sandwiched between the two parts, and the hole on the front is connected via a flexi pipe to a NACA duct in the bonnet bulge. If you want something suitably pimptastic, I suspect the easiest way to do it will be a CAD file of the part, and the services of a pattern maker and a laminator. Getting a good cosmetic surface finish with carbon is properly difficult.

    The internal surface matters more, since I'd hope he'll spend more time driving it than looking under the bonnet.
