Godawful colour Mick, especially the chainguard...

My 500 has a headlamp switch like the one on the LH bar - never seen another like it (until now)

So, do we have to guess which "K" model of the components in each picture? ;)

Idiot lights are K2 onwards, as before they were integrated in the instrument. Brake caliper is K1. K0's caliper was not painted black and from k2 on it had some kind of "mudguard" to avoid water splash. The headlight is an interesting mixture. K0 and K1 had headlight ears and headlight shell with the same colour than the tank and sidecovers. From K2 on they decided it was expensive to keep so many different spares and all had chrome headlight ears and black headlight shell. The taillight is K1. I know in the european version it had the black version (with three-point attachment). Sidecovers are K1, and they were that way until the "CB750" badge changed for a bigger one (can't remember the year). I don't know wether the seat is from another bike or is a repro cover.

Raul-

Sidecovers are K1-K2. In '73 (K3) they were changed to the ones with the rectangular black background.

Looks mostly K2 Mick, although the frame looks older, the K2 on had the brake pedal adjuster bolt, which yours doesn't have, so it could be K0 or K1. I like that seat mate, looks very comfy! Cheers, Terry. ;D

I was feeling sorry for myself because I couldn't afford new bike boots, until I met a man with no legs.

So I said, "Hey mate, you haven't got any bike boots you don't need, do you?"

The front end is most definately a K2.  K2s were the only ones to have chromed headlight ears which had the turn signals mount like the K0-K1 (K3 and on the signals mounted in a hole just aft the headlight mount).  Also, K2s were the only ones to have the instruments mount like the K0-K1 (directly to the upper triple clamp) and have the warning light panel/handlebar clamp combo.  K3 and on the instruments mounted to a bracket which was then mounted to the upper triple clamp.  The painted brake caliper and the upper area of the lower fork casing are also suggestive of a K2.  The light switch on the left handlebar is not for the US.

The frame is K0-K1 as it's missing the brake pedal stopper adjustment tab.  The brake pedal though looks to be K2 or later (not too sure on this as my recently aquired K1's brake pedal also has a tab that should sit below the brake pedal stopper adjustment tab on a later K bike).  The tailight, rear fender and rear turn signals are K0-K1; with the tailight being of the US variety.  If the chain guard is plastic it's a K2; if steel then even later.

The sidecovers are K1-K2.  Or, at least the "750Four" script is.  The winged badge below the script will be red for a K1 and orange for K2 and on.

That's about what I can figure out so far.

I disagree (just a little). Diamond wing badge was red for candy ruby red and orange for candy gold in K1. Chainguard was metal from K2 on if my memory and the books I read it once are correct.

I disagree (just a little also).  You might be right about the chainguard but the diamond wing badge no.  Only K1s were red (on all color options) while all subsequent models through K6 were orange.  Besides, there are two candy gold K1s on ebay right now, both with red badges and both appear to be original.

You might be right about the badges. I checked the parts manual and it shows different part numbers for K1 and K2. Besides, there is no indication about colour (as opposed to sidecovers or tanks)

They wouldn't list the color.  What differentiates them is the parts code.  300 for the red ones and 341 for the orange ones.  I've got an NOS set of the red ones and the parts code is 300 and you can still get them.  Now finding an NOS set of the orange ones (that aren't repops) is a whole different story.
