Bridgestone BS-7: Tank Idea

The spare Bridgestone 90 Sport came with a fuel tank, which is an interesting shape not shared with the 90 Mountain and 90 Trail models. It is longer, lower, and somewhat pointy as shown below:

It happens to fit the BS-7 frame quite well, and extends backward about four inches more than the BS-7 tank. I think it could work with a cafe style seat. Oh, and a set of Honda Trail 70 rear shocks fit too, and are about 1/2" longer with a bit more stroke. I also like the exposed spring look.
