Very interesting Ash.
Makes sense that they took it there as soon as something tangible was available to show, what with history of them in USA Honda network asking for a multi cylinder engine to advance from the 450 twin as request from marketing position etc.
The notes say "only CB750" to use accelerator pump on carbs .... probably don't know about the F2 then, and also Keihin made
Interesting about having a Hyvo primary chain on that one only too. Last development of this bottom end, going into RCB racer, went to gear primary drive with a idler intermediary gear to keep the gearbox rotation in same direction too.
