Trigger, the spanner size was because Honda used Japanese metric standards not ISO metric standard, you would have really hated the big tankers built in Japan, it was a nightmare after drydocking a German built one in Yokohama
All rather confusing for the restorer as the fastener Part # does not specify the bolt’s finish. This arvo I googled the common part # for the starter cover bolt (CB750, K1, K2), and was ‘shown’ very ordinary (Honda packaged) BZP bolts. How does one know what is right?Moving on, I looked more closely at the Sandcast Starter motor cover plate, and noted it too (just) fails the feeler gauge check… ie there is a discernible 0.5mm gap. I’m beginning to reckon the plates are non-OEM as everything else looks correct and original.In the case of the K2 rebuild, and the new Yamiya plate, I’ve ‘fixed’ the problem by adding a thick SikaSeal adhesive base to the packing seal, ie raised it 1.5mm. For now, it’ll do until I get to the bottom of the issue….One last query; one starter cover plate is mirror chrome, and the other a brushed chrome finish. Which is original pls?
One nut that seemed to retain the chrome look was the upper shock absorber cap nuts and the big thick washers behind them. Another was the pinch bolt for the rear brake arm on the rear brake plate. Same for the gear lever pinch bolt, some changed but some retained the chrome one. Some fasteners do use an identifier on the end, modern Honda JIS screws for instance can be identified when they are black and also when they have a captive split washer, for use on handlebar switch gear for instance. Oh just thought of another chrome bolt, rear number plate bracket ones, the 4 which attach it to the guard, they tended to be chrome with chrome washers, as did the rear light ones come to think of it.
