Yea Matthew,
I'm honestly with you all the way on "keep it simple"; Honda did a great job. My personal failing is I enjoy electrics / like to tinker.... and so any excuse. (& anyways, 70's electrics is just like plumbing... without getting wet!)
In Norniron's case, he's fitting up rated coils... I don't know the spec but have read elsewhere that various aftermarket coils are somewhat more beefy / power hungry than OEM. There comes a limit as to how much current you should reasonably expect a switch designed to a lesser spec to pass... and so a relay becomes a necessary evil in such cases.
In the case of a breakdown attributed to a relay failure in this case.... a very simple roadside fix would be to disconnect #86 & #87 from the relay & then connect them together.... the kill switch will now feed both the coils & Electronic ignition directly.... ie we're back to the original wiring. Perhaps David, mark those two connections with dayglow or something & put a connector spade in the toolkit! (tho' modern relays rarely fail)
(or #30 to #87 would work... the ignition will now be permanently live... ie if the kill switch failed this would also be a get-you-home)

The Boyer system I fitted to the CB650 was a complete system, coils an all. Not one item of the Honda set up was retained. It cost £170 and was worth every penny. I could not believe the difference.
The engine started up instantly as you pushed the button, no delay.
The exhaust sounded crisper.
Throttle response was positive with no flat spots or hesitation.
Considering the CB650 came with electronic ignition as standard the difference between the two was a revelation.
It was like having an extra 100cc added to the bike.
I've used strobes and dwell meters to set up points/ignition but it doesn't matter how good you are you will not get the same performance improvements that will come with a full electronic system. If you take you time and put it in carefully you can then forget it, no maintenance required.
Don't be a dinosaur, go get a Boyer.
