Thanks a lot! I'm really happy with how it turned out. Lookin to get some different mirrors for it eventually and probably some smaller turn signals. Beyond that I love it. The noise from the transmission has not returned... so I'm not really certain what it was. My fingers are crossed that it never returns...
hapakev- To make the seat, I made a metal pan roughly the shape I wanted. I was originally going to trim the stock foam, but then I found an exercise mat, its really high density foam, about 1/2 inch thick and easy to work with. I cut out 2 pieces of that and glued them together with 3M spray adhesive. From there I made a cover from some heavy vinyl, I think marine vinyl? It originally had some small wrinkles but those have disappeared now that I have started riding it. If you want any photos of the seat, cover, foam, pan, etc I have some and can take more. Just let me know
