So it was a chain reaction?
My late K1 (engine 111xxxx) has the 18T sprocket, no sign of a chain guard ever having been fitted. I saw one one for the first time on a mate's CB750 diecast engine last week, it looked as if it was made from armour plate.The engine and frame numbers on that one are 103xxxx, according to John Wyatt's book that makes it a Dutch market bike, assembled after the Uk 101xxxx series and not a (so called) K0, which start at engine 1044848. It has the four separate carb cables.
From Triggers knowledge and experience, 103xxxx is a K0 and I have a shed load in for re builds from the states

He got the bike in bits and knows little about it, other than it's not a sandcast, and too low a number to be a K1.ETA: @ Trigger - We may be talking at cross purposes here Graham - when I say my mates bike is 'not a K0' I mean it was an original CB750. This whole 'K0' thing confuses the hell out of me. My original 1970's parts book has numbers for CB750, K1 and K2, and photos of each. At no time does it mention any model called the K0, and nor does the manual in Ashimoto's drop box. I'm sure I've read there was, as far as Honda were concerned, no such thing, though just to be awkward Wyatt claims it was an interim thing that they made a handful of. I know we all call anything pre K1 a K0, but as I understand it 'Original CB750' would be more accurate.
