carandclassic.com as a classified ad, not an auction

Very good point!

I'm swayed by the safety aspect of a yellow rear plate.

Even in daylight the colour yellow works.

If you watch old TV shows from the 70s, you never see late 70s bikes or cars with black and silver plates. This is because yellow and black were seen as modern at the time, and black and silver old fashioned. I’m not that old, but imagine being 17 in 1976 and having a motorbike, and your parents had a 10 year old car with black and silver plates, you’d want yellow and black ones to look up to date.

Hence my 1976 on a P and came with black and silver plates (installed circa 2021 by last owner) , and I immediately got Jepsons to make period correct yellow and black plates. They use the correct font, not the post 2001 Charles Wright font you see on later yellow and black plastic plates examples, the cheaper eBay kind.

Genuine NGK ones, I spent some time weeding out the fake ones and made sure they are genuine.

Further update:

On fully charged battery, the spark on all 4 got a little bit bluer, but the spark was quite small and dancing around.

Also, all 4 plugs look the same, so must be getting the same power etc?

no I don't have original points, I bought it with the electronic ignition.it ran fine when I bought it 4 years ago and even better after I had the carbs cleaned and balanced 2.5 years ago.

I’m not currently by the bike, but if you look at page 2 of this thread, there’s a photo of the electronic ignition.

No idea, it was installed on the bike when I bought it!

I meant what colour on the bike’s loom, as that is that’s I thought you were asking, not the colour on the coils themselves.

No set colour as it’s aftermarket, however whatever colour wire comes out of the left sided trigger should also be the same colour wire going to the coil firing 1-4 cylinders.

I can confirm that the left had side coil is feeding plugs 1 and 4. And the right hand coil is feeding 2 & 3.

However on closer inspection the sparks are ALL yellow in colour, not the normal healthy blue you get. Appears to be weak power from coils?

These are Hendler coils I bought:

That’s right Ted, electronic ignition.

I think this bike has Electronic Ignition reading earlier posts.

Just to confirm, that no.1 is on the left, as you sit on the bike and look down?

Is there a wiring diagram someone can post?

It sounds like you've mixed up the HT leads. The coil with the blue wire runs 1 and 4, the one with the yellow wire runs 2 and 3. I suspect you've got the left hand coil trying to run 1 and 2 and the right hand 3 and 4. Just get them in the right order and it should at least fire on all 4 cylinders.
