I forgot to mention I am still running points. And I've been riding this bike for years with no issues until now. I may just swap in a new condenser and see how it goes. It's a cheap enough experiment.
Be cautious about buying these condensors now: almost all of them are junk.TEC (Honda's contractor) makes good ones, still, but at prices that will shock you. This is due to the low sales volume compared to the old days. Avoid condensors made by Daiichi China in particular: they are junk straight from their box. There may be some out there from Daiichi Japan (before China got into them), those work OK. There may be some out there marked "FEW", these seem to be from Italy, and usually work fine.
I've actually had better luck using old ones from old OEM points plates bought from eBay!
I also make a Transistor Ignition that will run from the points, without the condensors, if it gets that bad. The 550 cannot support the Dyna S electronics, they use too much power by keeping the coils ON for 350+ degrees instead of 180 degrees of crank revolution, which uses up all the available battery charge power of the 550 when the headlight is ON. My unit faithfully follows the points (and stops their wear), making the bike run normally, electrically speaking: it uses 0.100 amp extra power, total.
