‘87 RT with 140,000 miles. Works great. So why am I writing? I’m scooting down the highway at 70 mph and each time I initiate a lane change and press either the left or right turn indicator switch the engine misses a beat; like a millisecond. It doesn’t matter if I hold the turn indicator or just ‘stab’ it. Cancelling the said action does not affect the engine. In fact nothing causes the engine to cut out except pressing either turn indicator. I was able to repeat this several times over the course of an hour of highway riding.

Now... when initiating a lane change at 65 mph (or slower), there is no momentary cutting out (and when I say ‘cutting out’, I am talking a very, very brief lapse of spark.

The way I figure it is there is something electrical going on or the bike just doesn’t want me to use the turn indicators at 70 mph.

Any ideas?

If the problem goes away with the blue/green wire unplugged from pin 1of the flasher relay (or the instrument cluster) that could be a pointer, you would loose the auto cancel during this test, not a biggy.

How do they Work at 120mph?

My girl went away to Oregon for a long weekend to visit her sister and nieces. I've found plenty to do in the garage while she's away. 

Does this count as a momentary miss?

Only if you missed her and didn’t Fully exploit the moment of freedom....

105° F. today...not riding at 70 mph or 120 mph. Troubleshooting will have to wait until cooler temps.

Surely my lifelong association with Miss Fortune counts in this matter

Just as long as you don't mind miss-behaving!

Rather that than Miss Happ another close friend

For clarification, how much briefer a lapse than very brief is a very, very brief lapse—twice as brief? What is the duration of your baseline brief lapse.

If the moto works great at 140K miles, it might be best not to overreach. Perhaps you're being affected by your own synapse activity stimulated by the thrilling simultaneous tasks of speeding and turning.
