Problems
Got a problem. Actually, I've had a problem for quite a while. It's been intermittent, no dealers have been able to solve it. Ducati Corp. hasn't been able to figure it out and I'm kind of in the dark.
All started about six months ago. Idling after warm up (at stop lights, etc.) the exhaust would sputter and cough a little:

To complicate things, my bike would idle high--sometimes with the sputtering, sometimes not. It didn't happen all the time and didn't seem to follow much of a pattern. By the time I got up to Seattle it was doing it more and more. They suspected it was a clogged cat in the exhaust and replaced it to no avail.
Hit up MotoCorsa twice when I was in Portland. They couldn't replicate the problem, but ran all diagnostics, etc. and found nothing wrong.
By the time I hit LA again it was happening almost all the time. I pulled the bike apart and found a vacuum tube (the one that connects to the front of the belly pan) wasn't connected. Reconnected it and it still had issues. I pulled the tank and viola--found the tank seal hadn't been properly seated, which could very well cause not only lean issues/high idle, but also could have pitted the valves (as air/dirt could bypass the filter).
Ducati Seattle had been the last dealer to pull the tank (while installing the new heat shield), which meant for 4k miles I'd been sucking in unfiltered air. (they also didn't reconnect the fuel overflow lines). I took it into Ducati Newport Beach. They did a leakdown test and decided to replace the heads after replacing the ECU.
Got the bike back and it felt like it'd gained an additional 20% hp and the high idle and the popping/coughing at idle was gone. Everything was fine for about 600 miles, then the engine would hang at 3000 rpm before slowly dropping to normal at idle. Then the popping started, then the intermittent high idle. Roughly 1000 miles later the bike was back to it's possessed ways.
For the past 300 or so miles the exhaust sounds clogged (kind of a restricted dirt-bike exhaust putt-putt), sometimes idles high, sometimes low, sometimes stalls 10-20 seconds after cold start, sometimes wants to stall at low RPMs (been that way since 0 miles), sometimes coughs. To complicate things even more, after one fill up the bike read that it was getting ~30ish mpg, when in fact I was getting about 20 (and I could smell fuel).
Bottom line:
Intermittent high idle
Intermittent coughing/popping at idle
Intermittent loss of power
Intermittent low idle
Intermittent stalling when cold
Intermittent hesitation transitioning from 0 throttle
Hanging idle (at 3,000 rpm) almost all the time
Sometimes really ...... gas mileage/fuel smell
Mileage higher on dash than real life (intermittent)
All things seem normal at cruising
Charcoal canister was punted (after this issue first began), vent line is vented, vacuum line is capped.
New ECU
New Heads
Up to this point the issue was just irritating and never threatened my ability to continue on my journey. But it's getting worse and now that I'm heading round the world and do not want to get stuck in Siberia. Thoughts?
