I made up a puke bottle for the Bird,and wanted it to be noticed as little as possible.Everything will be painted black before final assembly. Didn't cost much, I used a over flow bottle from a motorcycle, and some left over aluminum.

Painting it black will really hide it.

I've see people mount them inside the inner fender and bolt them to the fender bolts that come through the inner fenderwell. Then paint black.

That worked pretty well.
