Hmm... at first I thought this 'BAR B' was just a typo: a clerk at the Honda office had misread an 8 handed to him in handwriting by someone from the workfloor and took it for a B. After all, it's an 8mm wrench, isn't it? But by and by I changed my mind and by now I kind of lean towards Gordon's interpretation, that it is ment for the brake bleeder and then the 'B' makes sense ofcourse: 'B' for brake or bleeder. Only... too bad the bleeder on my model has a 7mm head. Hmm, interesting... To be continued.
Now we are on it, does the '#2' and '#3' in screwdriver denominations refer to an actual size or is it just a ranking order?
