SOHC IGN COIL REPAIR -- DIY CHEAPO REPLACE HT LEADS Also N.D. HONDA TWINS COILS
Seabeowner:
Thanks for posting this. Most of us with only one or two (or three) bikes only come to this problem rarely and can make mistakes at the first attempt. The pictures give me the confidence to get on with mine.

Here are a few pics of my coil rebuild. It's not pretty, I've still got to file back the putty but it all worked well - very pleased!
The one word of advice I'd give would be to use blu-tac instead of tape to make the barriers for the resin. The tape allowed quite a bit to ooze out before it set and made quite a mess, however the blu-tac contained it perfectly. It's a bit of a pain to get it all off of the resin before adding the putty but overall the results were well worth the efforts.
Thanks Ash!!

that looks good,when I replaced my coils I chickened out ,
and got a replacement set,
they look very usable,and as they are hidden under the tank,the finish is not quite so important.

Great stuff Roger . One trick on the epoxy putty is to mould it to about the correct shape and let it cure for half an hour then moisten a rubber-gloved finger and smooth over the surface. Power file /wet'n'dry then satin paint will sort out aesthetics on yours ( if you are bothered ;)) .
Problem with 'replacement' coils is that if they are used and even off a low mileage bike, the PVC outer of the HT coil will almost certainly be really hard and brittle after 40 years.
Give me a couple of weeks and I can duplicate my tester so you can spark test at full rate, off the bike and give it a 'soak' test ( then pass on to anyone else who wants to use it). All you will need is a battery or 3A power supply, no test gear like I used.

Sounds like a plan!
