I have finally gotten back around to messing with this project.
I built a frame to hold the battery and support the new tail.
I settled on a cbr 600rr tail section and seat. They are small and fit with the tank. I had made a tail out of the old tank but it just did not look good having a rounded tail. I used some plastic to mount the non-functional passenger seat. I will probably replace the seat with a shell.

The seat pan fit very nice.

With a hole for the seat to clip and a few rubber knobs the seat is mounted.

I have moved all the electric under the tank. I have a tail light and blinkers ready to mount. I want to have the bike back on the road by spring so more updates should be coming.
