Hammer92 Posted October 14, 2022 Share Posted October 14, 2022 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! Link to comment Share on other sites More sharing options...
