Seriously though I’ll source two units and give it a go. Seems it will cost around £35, so might still go the Hondaman route if the group purchase comes off.

Why not go one better Phil .. get something like this in the link and a build CDi like I did for my 1st 400/4 (from York BTW XDN 128R and still out there on SORN but listed as Red and it was Varnish Blue when new).
It was based it on the Kwak H1 CDi but the H1 had a high voltage winding coil on the alternator so i built a 400V inverter to generate the HT instead.
Something like this:- https://www.ebay.co.uk/itm/253621579134
I did over 20k miles with that CDi on it and it was still fitted when I sold it in 1980.

If that one is a CDI, I don't know if I would want one. What I've heard - so, it's not from personal experience - the delivered initial ultra short Volt peak is very high, but there's practically no burn time, so if the initial peak misses for some reason, there's no reserve. CDI (thyristor) works well on some bikes like two strokes (?), on others a transistor EI is favoured. Again, this is from hearsay.

Well my 400/4 never missed a beat in 20k miles... just saying
CX500, Superdreams etc had CDi based ignitions.

I’m sorry to disillusion everyone but I’m actually massively allergic to fish, no I’m not kidding, anything out of the sea makes me very ill indeed. My son brought home a curry a few weeks ago and it must have had fish oil in it or something, my skin felt like it was on fire all that night, I had to keep throwing up to try to get as much out of my body as possible.
I had a kidney test a few years ago where they inject you with iodine and watch to see how long it takes your kidneys to clear it, as iodine is fish based evidently I had to have a consultant present in case I went into shock but it appears iodine is ok with me.
Roo, Mark says the flat rate box can take another module but no more. So I’ll add you on, be aware though that we may get customs charges, you still ok with that?
Sorry for those others who were interested but nothing stopping you from a little group buy yourself, I reckon you could get 3 modules in a box, it’s only because I’m buying the fuse box as well that the limits 2
Sesman:
That’s ok oddjob. Thanks taking time to make the enquiries.
Sesman:
Just a quick and novice question deltarider. The kit claims to have a maximum current rating of 4A. I’m guessing the nominal current draw for the original system is circa 3 to 3.5amps with OE coils? Is that uncomfortably close or are the units generously thermally rated in your opinion?
Apologies for such a basic question, but my electrical knowledge is pretty rudimentary.

'Roo, Mark says the flat rate box can take another module but no more. So I’ll add you on, be aware though that we may get customs charges, you still ok with that?'
Ken, if I remember right, Mark put 'repairs' on the customs docs - I didn't pay customs, just arrived through the post. Fingers crossed, the same applies to your order!
