Okay!
Just another try.

Thank you

But my dear, since you seem to be unable to deliver, I will give the " But "I are engineer" a little help 8)
System Too Rich,
Possible Symptoms
Irregular behavior
Possible Causes
Fuel system
Excessive fuel pressure
Leaking or contaminated fuel injectors
Leaking fuel pressure regulator
Low fuel pressure or running out of fuel
Vapor recovery system
Air leaks after the MAF
Vacuum leaks
Improper seated engine oil dipstick
Stuck EGR valve
Oil overfill
Cam timing
Cylinder compression
Exhaust leaks before or near HO2Ss.
You will be able to implement it 8)

We have a winner(s). Pat yourself on the back if you thought the bike had a bad O2 sensor. This one's for you, Gunleif.
Replaced the O2 sensor despite my doubts, and the bike started right up, idled smoothly and revved easily. Only ran it 20 seconds as it was getting dark.
Cue the tune... "on the road again, just can't wait to get on the road again"...
To sum it up...
Bike ran poorly, suddenly, on cold startup in the afternoon. Two header pipes cold, exhaust sooty, catalytic converter glowing. Spark plugs evenly sooty, original O2 sensor black.
GS-911 reported no codes set in ECU despite that this was probably a gross violation of emissions standards. O2 sensor voltage steady at 0.8 or so.
Replaced coils and plugs, no change. Replaced O2 sensor, alles gut!
Disappointed that the ECU did not detect a problem. Good that the realtime plot of sensor voltage showed it was bad (though I thought it would fail at zero volts, we live and learn).
Replaced
Gunleif:
Nice :)

That is exactly why I asked you to have a look at the O2 Graph. That would have told you whether the sensor was working or not. That was my first reply to your query. Look it up. Reply #2.
