You sound like a man after my own heart. The bikes are cheap but they kill us on the accessories.
I've been thinking about how it may be possible to put together a nice low budget air dam with some sheet aluminum and ingenuity.
Shouldn't be that hard to figure out how to mount it once you have the basic layout. You could use poster paper to work out a template to use as a guide to cut out the aluminum. Bolt it together with machine screws or pop rivets.
Polished or painted it should be an inexpensive yet impressive project. Heck you might even be able to bend your sheet aluminum so that any pop riveted seams would be underneath and out of plain view.
If you can work a little fiberglass, that would give you even more flexibility to work out something.... Just thinkin' out loud
But first things first. You've got that fairing to get done.
