OS 80 4c “Pre OS 90”


RARE FIND OS 80 Four Stroke! This is the predecessor to the OS 90 Fs which is the Predecessor to the Surpass series from OS. This was only sold in Japan for a unique 13cc class back in early 80’s. This engine runs awesome turning an MA 13-6 at 8600 rpm and idles at 2400 rpm. Twin needle carb is adjusted and engine has been bench ran on my test bench. You can own a piece of history here! Price is $200 shipped lower 48.
