That said, a fair number of points airheads experience issues relating to wear and misalignment of ignition components that aren't easily fixed - like worn mechanical advance units, or bent camshaft noses. This happened to me.

So I was researching electronic ignition units, and we should note that there are some major differences between units. Like how the advance is handled, whether it can be adjusted, where the pickup is mounted (crankshaft or camshaft), and what sort of pickup (hall / photo gate). I ended up ordering a Sachse ignition from Germany (similar to Silent Hektik, and Sachse makes Enduralast's ignitions) for several reasons.. first, it mounts on the crankshaft, so issues with the timing chain or camshaft nose won't affect timing, and it allows me to keep my points in place as a backup. Second, it is photo gate triggered, which seems desirable to be because I often hear of hall sensors failing, though that could just be because there are more hall sensors out there. Advance is handled electronically, and there are a bunch of curves to choose from.

I'll report back when I get it mounted up. But I should say that if I weren't having issues with my points, I wouldn't have bought it.
Crank mounted has many advantages and I like your idea of leaving the points in place, why didn't I think of that? I had a crank mounted system that did the advance electronically. This was a couple years ago and they were the new rage then (still haven't been around for Airheads that long). So I had two problems with the one I had (sorry I forget which brand this was). #1 was the construction was flimsy. I didn't have it long enough to experience problems tho because #2 is why I got rid of it. #2 the electronic advance was a tiny potentiometer with ten positions. The instructions said to start at something like 3 and advance the switch till you had the performance and driveability you wanted. With out pinging , of course. Boy, did I have fun with that switch. I was cranking it up more and more. I had a tight rebuilt engine (still have it). I was tearing down the neighborhood streets. I was waving at the neighborhood kids as I speed by. I was the incarnation of the Speed Racer on my R90/6. Then it started pinging. I couldn't turn it down far enough or fast enough.

I has bad hearing. I talk loud. I didn't get along with this thing that gave me feed back in tiny whispers until it started screaming at me. I just did not think it was for me. I actually think this is a good solution for riders that still have most of their hearing except for another thing, It is expensive. So even though I had the money back then when I owned this I got rid of it. I really don't think it's for most of us Old Guys. That's all.
