My bet. The usual $4 network cable screwing the $4M data center
Ok, so I just got off the phone with Ducati's HQ in Cupertino. First off, they are doing everything they can. That's not me quoting what they said, that's my summary after our call(s). (The Pope and the four horsemen of the apocalypse were mentioned as being involved....)
In any case, guy who spent all day with my bike on Saturday is a Ducati Jedi from HQ. The diagnosis: Rings and Pistons.
I've heard of bad rings causing high idle on a two stroke, but only a rough idle on a four stroke engine. However, it's possible that the electronics compensate for idle anarchy. But I'm not the guru so I'm not going to speculate.
AND - Before everyone goes nuts thinking the 1199 only has 30,000 miles before a rebuild is necessary, keep in mind that a prior dealer who I won't name did not seal the airbox properly when they put the tank back on during a service. Unfiltered air into the engine does things like pits valves and destroy rings. As long as your airbox seals are tight, I highly doubt any of you have to worry. (Jeez, I hope my cylinders aren't scored, too.)
Parts should arrive by the end of the week or beginning of next. Thanks everyone who reached out to me with suggestions and recommendations and offers both on and offline.

OK, I lost with my network cable bet then
But, didn't the Not To Be Mentioned dealer change the heads because of the very same symptom?
I might be lost in this drama, so help me in the chronology of the eventsDucati Newport Beach changed out the heads--they were not the ones responsible for the airbox seal-issue. An engine tuner buddy of mine at the time the heads were replaced actually said, 'if it pitted the valves, the rings are probably shot, too'. Looks like he was right.
As for the engineer tasked with the fix--I know he's worked on factory WSBK bikes before, so who knows, maybe I'll even pick up another 40 horsepower when it's all said and done.
In this order:I might be lost in this drama, so help me in the chronology of the events
1) You had unstable idle issues.
2) They changed the heads and sleeves in trying to fix. bike ran fine for 1000 miles.
3) Somehow the airbox seal did not end up being sealed correctly.
4) You ended up with the same idle issues again because of dirty air fscking up the rings.
Is that close to the facts?
In this order:
Coughing/popping exhaust at idle
Then high idle
I removed the Charcoal Canister. No dice.
Dealer replaced exhaust thinking CATs were clogged. At the time they also replaced the heat shield (I asked for just the side covers, not the new heat shield), but they put it all on, which involved removing the tank.
Drove another 4k miles.
Took it in several times, but they couldn't replicate the problem.
I replaced TPS. No dice.
I pulled the tank off to see if there were any vacuum leaks. Found the airbox hadn't been sealed, found one vacuum line hadn't been connected and discovered the fuel overflow lines hadn't been connected, either. Fixed it all, but again, no dice.
Let Ducati know about the seal. They did a leakdown test and replaced the heads and ECU. Bike was ok for 1k miles.
Took it in again. They couldn't replicate problem.
Drove it to the shop while it was doing it a week or so later. Ducati regional technical director happened to be onsite. (Yes!)
Thought they found the issue with a valve in the exhaust. Fixed, but no dice.
More big guns spend a couple days with it and now the verdict is: rings/pistons.
When you pull the tank the seal stays in place. Instead of bilateral symmetry, a portion of the seal on the right side of the bike had been squashed in. So much so that even after I pulled the seal off it remained in that squashed position. Happened to be in exactly the place you wedge your hand in when reconnecting the fuel quick release, indicating that the last mechanic reconnected the fuel lines, he pushed the rubber over and into the airbox, snapped the connector, then pulled his hand out and left the seal down where it wasn't supposed to be.
I cleaned out dust and even some leaf particles. Wasn't like the whole interior was covered in filth, but there was debris, which most certainly should not be in there.
have your cylinder bores checked for scoring
