I've been trying to figure out what to buy for an electronic ignition for at least a MK III Commando and possibly a MK II, which has points, as well.
Back in the 80s, I installed a Boyer on the MK III because the second mechanical advance had the notch wear, been filed out, etc. I never really liked the Boyer, due to the slow and never ending advance curve. Ended up advancing to like 32 at 5K to salvage low and mid range power. I don't know if they are still like that. I didn't care for the (I think) NEMA G10 board, which made crunching sounds when the plate was tightened. First test drive, it moved, because I didn't tighten it enough.
Short story is that I want a more aggressive advance curve. I don't know if a current Boyer is like mine.
I'm seeing a number of options, including the Tri park, Pazon, and Vape. The Vape is pretty expensive, and seems to fit Norton, Triumph and BSA. Maybe so, but one is supposed to run 28 degrees full advance, and Triumph 39 degrees. as I recall. I don't know that the same curve works equally well on both machines, assuming its the same model. I don't hate points except for the troublesome and apparently not available (formerly expensive) mechanical advance. When I had points, I ran it for years with a dead battery. The old Boyer likes volts. It also broke a wire off one of the pick ups, which was the only time that bike stranded me.
