I have a 1980 RM100 frame, complete seat that needs a new cover, of course, air box with boot and a 1977 RM aluminum tank. I also have a set of RM465 triple clamps set up for the frame with some '82 YZ250 forks that can go with it. It was a project that never happened.
If there's any interest in this let me know and I'll post some pictures. It's located in South western Indiana. 47620.
