For simple transport you can beat the plastics off, and make a seat from plywood or whatever. The original seat foam, and cover are good downers for parts.
I enjoy my stripped down 4t more than any other bike I've ridden. I think I have spent twelve cents on building it, 4-5 years ago. No really I have about 300 bucks in it over 4-5 years. 2 cranks, and a big bore kit/exhaust from FleaBay. Oh... 2 CDI's, 2 carbs., and four tires.
