I found a photo of a Roadking off the Procharger website.

I am trying to find some better photos of the fairing set up that was used.

 

The faring looks like a custom job. Looks like the bike has a turbo on it.

 

That fairing looks alot like the one I got from JC Whitney many years ago, to put on my old CB750F. Other companies made similar style fairings, usually advertised as a cafe or sport fairing. Search cafe fairings and I'll bet you come close to what you need.

 

That looks like a Ness fairing.
