Always annoys me the stripes on tank don't look right.

Not necessarily, but realise you'll then have a total of 20kΩ resistance in a circuit... Personally I consider that a lot and it is not needed. The French manual, that has been composed in colloberation with Honda France, advises to replace plugcaps when they read 8kΩ or more. Claims made by some members of the international forum - and nowhere else! -that adding resistance is benificial for spark duration, have so far remained unproven. And even then it remains to be seen it will effect in better running.

Your back plate securing screw is nicely in the middle of its adjustment range👍

As the others say, a crappy time you have experienced but great you are able to share your feelings on here. Hope that helps you in dealing with things. Take care.

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.
