Fuel for Yoshi CB750 F1

[Tapnell]

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.

I've run several Honda and Suzuki fours on this modern gunk that they try to convince us is petrol and had no problems other than starting if the bike is laid up for a while without running . Not sure if the compression ratio of your Yoshi will give any trouble though . Best of luck.
Will.
