Good post Bryan - eventually I think I will end up fitting Dyna coils so was very interested in what you were doing and why - I like the idea that a dodgy lead can be replaced without all the expense and shenanigans that you get with the standard setup - kev

Why change?
1. the 30 year old units plug leads were getting shorter and shorter
2. there might be a few more horsepower in it for me
3. I will be fitting the Sachs electronic ignition down the track so 3ohm coils will be needed then

don't laugh at my stickers - there is madness in my method
As you can see the old units are different (the smaller is a 2nd handie with XS1100 RH written on the side) - and they tested differently also - neither giving the optimal test reading.
I removed the BALLAST RESISTOR and set it aside. Join the wires that connected that and insulate the connection - heat shrink is perfect to protect and insulate.
So anyhoo.....
Thus far I've only been able to source silicon HT leads so thats what is fitted today (I have 7mm wire leads arriving by mail so I can use my NGK 90degree plug caps (I wonder which will give a higher HP reading)
As can be seen, the mounting holes in the DC1-1 units are at right angles to the OEM so brackets to be fabricated to facilitate mounting
The DC1-1 units do not come with wires but do come with fittings so make up some leads...

and fit them - mine fitted without difficulty - fiddely though....



I don't like the silicon leads and caps - too long....inelegant.....


well there it is - I've been for a squirt around the block - sounds a little crisper maybe...
I'll put it on the dyno at CONCOURS in a few weeks
the workshop.....
