Has anyone done any crack repair to factory side fairing (or any other color molded factory pieces)? Someone tipped my bike over at a gathering and it sustained some small cracks and scratches, and I'd like to repair them if I can... And then I think I will just vinyl wrap them.

I had a friend plastic weld the back side of his r1 fairing and then wrap it after it looked pretty good, you could also fill the small crack on the front with some silicon before wrapping and it would likely look new. I think he had plastic Rods for his arc welder if I'm not mistaken.

No but there are videos on youtube on how to weld plastic.
I'd still put something behind the crack for some additional support.

Pretty sure the fairings are ABS.
Harbor Freight sells a half decent plastic welder (at least it seems so to me, having never used one before)
It comes with basic instructions, but you'll probably learn more on YouTube.
Get some ABS filler rods, preferably a little thinner than the area to be welded,
Practice on a piece of ABS about the same thickness as the fairing first, and pay attention to what heat setting works best.
You can probably find a cutoff piece at a plastic supply store.
If you can get your hands on the correct angle countersinking tool, you could back up the repair with a piece of sheet metal, assuming the area doesn't have any compound curves.
The countersink would be used to sink the heads of flat headed pop rivets below the surface.

IF it is ABS, you can repair the crack with ABS pipe cement. Find an old PC monitor, TV or boom box, most of them have housings made of ABS too. Cut apiece from that to bridge the damage on the back side. With ABS material and ABS cement, it increases the odds you will get a good solid bond by using similar materials. Some cements have a reinforced formulation and are in black. If the parts aren't flapping, you can also just cut a beveled relief in the crack on the "non public" side with a Dremel, similar to what you would do for a weld in metal. That reinforced stuff does pretty good at filling. If you need more material to fill the gap just cut really thin strips, or use the plastic sawdust ( made by the saw when cutting the housing of whatever electronic device you used.)

Used scrounger's method on a Triumph fairing years ago; still solid when I sold the bike

Duramix is also a great for plastic repair. A little pricey though. I've used it to mold in video monitors for car systems.
