Japanese Bikes / Fuel for Yoshi CB750 F1
« on: March 28, 2006, 03:31:14 AM »
I'm about to run up my old faithfull 812cc Yoshimura C750 F1 which I have owned since 1977. It was last fired up in 1995 on the old leaded 4*. My question is, how do the old fours cope with unleaded or will I need to use a lead substitute? Trust someone can help.
