Did you make that intake yourself? Any chance I could get my grubby little hands on one?

Well, yes and no. The manifold is available from "joe-wiseguy" on here, in several different configurations. Mine happens to be the cafe/tracker config. The carb is a Mikuni 36mm VM round slide that I jetted for my application. The filter is an Mike's XS K&N clone, and I made the air shroud and modded the side cover to accommodate the setup. If you search on "conversion", you'll find a thread on my single-carb project that has more info and documentation of the process.

Thanks for the interest!
