Most parts can be had from Suzuki, or Suziparts. Plastics etc easily got from Vintage Suzuki. Pipe wise... Very rare, but a Circle F TM125 pipe would fit with a little help. If you are really stuck, I have an S pipe that is missing the header section and muffler. Being very thin they rust away quickly. Mine could be good enough to build up a pipe, but it would take time, money and a knowledgeable pipe builder.
