Teds new project a CB500 K1 mostly version 0.5 circa 1972.

Thanks Julie, I agree the bars in the photos clearly look higher than the UK ones even in the schematic sketches they look unlike the UK bars.

These are pictures of my USA K0 as I believe Honda installed it:

Ignore The small wire loom going near the cable in the 2nd picture. This was a standard USA mod where they raised the ignition switch to the bars.

I have three new clutch cables:
Andy Cepok UK type:   1.03m
DS UK type:    1.07m
22870-323-020 still in bag that I think is USA type:   1.12m

I also have a note saying UK type should be 0.99m (3ft 3in)

You can also see the throttle cable passing the other way through the gap above the coils.

That is an interesting photo as though the throttle cables are on the left side of the frame they are not visible as routing between the clock bracket.

The clutch cable route is the one I will follow as it's how it was when I bought the bike.

Just to add the pics are with US bars. I have now fitted UK bars and the new cable follows the same route...I think.

Bars genuine or copy Ted? Sat with the dots aligned?

My bars are not genuine Honda so no dots to align - I have the location holes for the switches & cables so the bar position is basically what looks level & right with the levers etc.

I'm happy with my throttle action even if it's contrary to the manual I need to fit the clutch cable route so it works properly as it did before even if it means the cable loop near the clocks.

Surely that would depend on where you measured them from? I know mine is a genuine UK one from around 1979, back then I doubt any parts depts had any USA stock as imports were almost non existent back then. There is quite a large mark on the sheathing of the cable, right through to the inner braided steel outer, I'd imagine that roughly complies with where yours passes around the tank mount. Next time I fit the cable I intend to split some fuel line and position it so the cable gets some protection.

Those two  cable lengths are shorter than mine M {48" - 1.22m) I have located one on e-bay a. Wemoto part that is 40.5" including the adjuster (1.02m) worth a punt at £12.

Why not just buy an original UK one Ted? always better quality.

It might not fit (my bars are not genuine) on the routing I want so decided a DS one (22870-323-621) was a bit pricey for a trial at £54.29 plus postage. At just under £12 it's cheap enough to try plus the seller took the trouble to measure it up for me.

Interestingly my old cable still has the part number on the outer sheath it is 22870-392-000 not sure what model that was for originally. Not sure what -392- part refers to - google says a CB750 A

Replacement clutch cable arrived this morning - fitted at lever end routed throught the instrument bracket gap over to the right side of the frame - loops past the bottom of the coils dropping just right down between the carbs 1 & 2.
The cable is around 8" shorter now fitted at the bottom end.

New cable has the extra outer protective sheath plus the bottom ajustment shroed - presumable that is to enhance cable protection when it passes through the frame or it could be for between the carb banks.

Good to be rid of the 8" of spare cable!

All the genuine clutch cables should have the extra outer sleeving that starts nearer the bars end. The black rubber block (grey on early cables) just slides down as far as it goes at the engine end.
All my measurements were outer cable only, including engine end adjuster.

They were spot on thanks I am happy now with the correct length clutch cable,  the routing is I believe now correct - the clutch action at the lever seems to be fine though clearly can't be sure until its a runner but the lever action feels spot on with adjustment available in either direction if needed. 👍👍😁

[McCabe-Thiele (Ted)]

Now that the clutch route is correct it's nagging me to change the throttle cable routing - I definitely can't go down 
via the instrument bracket but could do much closer to the correct route - from the bars down through the front forks to the left side of the frame, crossing over to the right side at the coil gap to the carbs.

With my luck the currently smooth throttle action might be lost.
