I bought a parts bike for the plastics and other bits that I was missing - the seat came on the parts bike.
I bought the bike from MD (yeah, shipping was not an experience worth remembering), and the guy I bought it from was the original owner. The wheels were bead blasted, the forks were polished, and the upper fairing and belly pan were new. But (and of course I didn't have the foresight to ask this gem of a question) the bike had been sitting outside for several years. The wheels, cases, forks, and every unpainted surface on the bike had oxidized. There are rust holes under the paint on the tank, and the seat was hazed from exposure.
The plastics hadn't even been painted - they were gel-coat black from the factory, with the tail, side panels, and tank painted to match. All of the polished bits will need to be re-blasted or sanded, but the seat vinyl is in great shape, and its color came back nicely with a little S-100.
The work on the seat was well done, and it's a combination of grained vinyl and waffled vinyl. It's about 1/2" too short, though - as if it was reshaped off of the bike and not trial fit - there's a small gap between the end of the seat and the tail section. But it looks sweet on the bike, and far better than the other "custom" seat I have (in the before pic).
As for the fairings, the cafe fairing was great, but it took a bit of adjustment to get it mounted right. It had far more protection than the factory "E" nose fairing. I fabbed some brackets to mount a round headlight to the factory headlight ears, and made some more brackets to mount the cafe fairing to the factory fairing tabs on the headlight bracket. Wind protection was great, and the optics were good enough on the screen that a full-tuck was feasible (with some stuffing in the tank bag

).
After I'm through with this one, I'm going to put the donor bike together for my nephew for his 17th birthday (about 2 years from now). I've painted the second set of plastics the same blue, and will mount the cafe fairing to the other bike. I'll probably make some supports out of aluminum dowels to brace the windscreen against the bars, though (like a newer sportbike), as it tended to vibrate a bit at high speed.
With the lower clip-ons, it gave the bike a pretty sweet cockpit feel - like you were in the bike instead of on it....
The new fairing offers every bit as much wind protection without having to tuck. If I stick my hand forward into the jet stream, I can feel the deflected air striking right about chin level, or helmet crest level as it hits the rider. There is some wind at my shoulders, but the lower bars have me tilted forward quite a bit more than factory, so I don't notice it. Not bad for a small piece of plexiglass - although I'm sure that my mileage and power are suffering for having to push around what's basically a small, flat windsail....
Gotta go - delivery food finally arrived!!!
Thanks again for all of the compliments,
