Try resetting the adaptations.

Could it be that the cat was glowing red because of unburnt fuel flowing into it and then igniting/burning .....due to the faulty coils?
Honolulu:
Yes.
Poor combustion => excess fuel in exhaust => converter doing its job burning excess fuel => lambda sensor reading 0.8V
Exactly why I replaced the coils, and spark plugs, and coolant, while I was in there. This meant I had to acquire the vacuum tool to refill the coolant, and the proper 5/8" or 16mm plug socket (the one I had was too big). It's not a difficult job in retrospect, but given the complexity of the machine overall, I'm a leery of having to work on it.
Now that the "work" is done, and it still runs poorly, if a idle actuator reset doesn't get it right, I'm afraid I'll have to talk to the local dealer. The only one in 2,500 miles. Whose parts tech doesn't return calls. Bad sign...
Gunleif:
I think the O2-sensor is the problem. Put in a new one. :)

Gunleif:
Not one to argue, but 02 sensors aren't cheap, so why do you believe the sensor is bad? It only has 30,000 miles, It "ought" to last much longer. I think with it reading 0.8 volts, one coil bad, the cat glowing red, the sensor was correctly reporting a rich exhaust condition.
Is there a way, other than by substitution, to test an 02 sensor? I've heard of putting the sensor tip in a propane flame (need to remove from bike first obviously) and using a DVOM to check voltage, but I've never done it.
