Just a PSA.
I was riding, then wasn't. Engine stopped and I was on the side of the road.
Looked at it this morning, got some spare parts out and test meter, then went to work. Wam, bam, can of Spam, fixed in the AM. Spark plug cap was bad. Put a spare one on and the world is right again.
A reminder that they use resistor spark plug caps and they can and do, occasionally go bad. Supposed to be ~5K resistance. Mine was in outer space. I'll buy a new one later, the spares I have are all just as old.
