I now have about 12 working mk16 lumenition systems so should see most people out as not that many being ridden every day.
I also have a lumenition factory test set up which is rather interesting and a bunch of spares to repair when I am bored.

Subject: Re: Boyer ignition problem
Hope you are progressing in your recovery from Covid 19. My interest in this subject is that I have the original Lumenition ignition and at some point it will probably fail and will have to make some decisions about what to replace it with. Boyer/Pazon/Wassell systems offer a reasonably priced option. A new Lumenition system can be made to fit with some small changes to the base plate but requires a functioning mechanical advance and retard mechanism. A Newtronics (Piranha) could also be made to fit (they made a kit for BSA/Nortons at one time) which would require the mechanical A/R mechanism, but does offer the possibility of moving away from wasted sparks.
The Boyer system has been successfully fitted to several Silks with no significant problems reported and I am wondering why we now seem to have two systems with similar problems. Paul's Boyer was checked and tested and no fault found and the installation checked all to no avail. The Boyer Micro digital unit appears to be susceptible to RF interference which is why they require a 5k ohm resistor in the ht lead. Another source of interference could be the modern alternator rectifier/regulator putting high frequency ripple on the 12v system. I don't believe the old zener diode regulation would create a high frequency ripple and this could be the difference. Fairly easy to test the theory, just disconnect the alternator and see what happens. If it doesn't cure the problem I have run out of ideas!
