I have an extra set of R100 Nikasil Cylinders and pistons ... I will also have two bikes that will needs these ... eventually. I also have a post 85 final drive, a post 81 transmission, several clutches, and some heads that will also require similar long term storage. I live in Atlanta, and it can be 'humid' here in the summer. Things rust.
So how would you store these parts so in 10 years they will be usable and fresh?
