1 Missing until engine warms up Tue Oct 31, 2023 7:43 pm

1987 K100RT with a gazillion miles
I’m experiencing a very minor - but consistent - missing until the engine is completely warmed up (usually 10 miles or so) at which time the missing goes away.
I want to stress the missing is very real - I can feel it in my right hand grip - but the missing is not as pronounced as if I pulled a plug wire.
I am ready to start troubleshooting but by the time I am back to the garage (more than 10 miles), the missing has disappeared. As long as the bike is warmed up, the missing does not rear its head.
The bike starts and idles without issue (although I believe a “minor” miss may be difficult to detect at idle.
Miss is more difficult to detect under hard acceleration (before engine is fully warmed up) than it is at steady speed.
This is a new thing in my life. I considered an injector not performing up to spec (but not plugged) so I am running a tankful of Chevron to see if their Tektron will clean out any semi-plugged injector.
Ideas, suggestions, hints, etc. are appreciated.
