Hammer92

Hey all, new to this group and also the new owner of an old 350cc Yamaha project. Hoping someone could help me with clarifying something as I dig into the details of my new project. My frame and engine are stamped: (R1-04392). Is what I have a 1967 Yamaha YR1? If so, does anyone know how many Yamaha produced for this year? Any and all help/insight is appreciated!
