TOPIC:

When I replaced my spark plugs I discovered my spark plug end-cable caps do not accept the usual spark plug ends. I had to unscrew and remove the top of the spark plugs. Thus, the connection is not perfect, though it seems to be adequate (the LHS is looser than the RHS. I've included a picture looking into the end-cable cap and it's clear the extrusion to catch the spark plug end is not much at all).

This led to a bit more digging.

The end-cable spark plug caps attach to the HV cable by what appears to be a bit of a bodge: the cap is pushed into the insulation of the cable, where it makes its connection to the copper.

Researching further, I don't think my spark plug caps are original. They are brown, and from what I can make out on the photo on the front of my service manual (I've included a zoomed-in picture of that here), they would have been black when the bike was originally built. That might explain why the caps don't fit the spark plug tops.

My questions for you please are:

1. Are my spark plug end-cable caps non-original?
2. If so, does anyone know where to get the correct end-cable caps that will fit the spark plugs properly? I've tried eBay - all US so expensive postage.
3. Is the means of attachment to the HV cable a bodge?
4. If so, Can I replace the cables without a complete replacement of the starter motor?

I've attached a few photos to support my words above.

My bike is a 1981 KZ440-A2 (as far as I can tell) Frame No KZ440A-026673.

The reason that spark plugs have the screw on caps is that different manufacturers of plug caps have different preferences (it's not a bodge)
Brown caps are normally NGK replacements for the originals
The cap having a threaded spike which screws into the end of the HT lead is also a normal method of fitment (not a bodge) if there was a poor connection here, with 20kv jumping across there would be significant signs of burning
Not sure how this relates to the "starter motor"   

Thank you for the prompt reply. 

I meant ignition coil. 

Unless you have a problem there is no need to replace the leads or the coils (they don't look in bad shape from the pictures)

I was going to replace it only to get ones that snap-on to the out the box spark plug, with its cap on. Particularly given the LHS seems loose. I found these: NGK LB05F Resistor Spark Plug Cap amzn.eu/d/jeomUbN

Your missing (or not captured in the photo) two HT rubber caps, they are shown in the parts fishe you posted as numbers 92071 & 92071A. The fit of the plug cap to both the HT wire and plug will be greatly increased with these two item and will seem less (bodge) what ever that is. 

“Whatever boomer”

92071a I do have. 

I don’t have 92071. I think amzn.eu/d/jeomUbN has that included. Would you agree?

Yes, the Amazon item is complete, only fit resistor caps if your leads and plugs don't have resistors

Yes, the replacement you posted has both item. They will dramatically increase the fit/function of the cap.

7mm copper core wire is what Kawasaki used.  If you shoot some WD-40 under the wire outer protector, you can then pull it off and install it over your new wires.

Thanks. 

I have NGK B7ES plugs. I think they contain resistors. 

I don’t know about the cables?

B7ES do NOT have resistors.
BR7ES DO have resistors.
So if your plug caps have resistors you use B7ES plugs. 
If your plug caps do NOT have resistors you can use either plug model. 
HT cables do not have resistors.
