I ride a 2014 model. I never had any deceleration issues with the throttle, instead in my case during acceleration the bike wont move more than 4500 rpm. This is also a very serious safety issue, as i escaped narrowly from an accident. The remedy is; pull over, switch-off the engine, remove the key, then start over. First time Ducati said its just a matter of software update. But second time after 1 month the issue came again and that time, the bike wont even rev at start. Finally Ducati changed the throttle sensor and since then (500km and 3 weeks) all seems fine.

In my case, there was no rain or water services did. Here it will rain maximum for 5 to 10 days a year.

I wonder if it's the way the gas tank was filled. The other day I rode 151 miles on a tank of gas. I managed to fill it with 3.5 gallons, by doing the usual: fill it, rock it, watch the level go down, fill it some more, rock it, watch the level go down, and then when it won't drop any more because the air is burped out, fill it to the bottom of the filler neck.

I then went home and parked the bike in the driveway. When I went out a little while later, the bike would start, idle would slow, then it would shut off. Repeated that a couple of times. Took the key out and opened the gas cap. I heard a rush of air, like vacuum releasing. Fuel actually dribbled out of the gas cap itself. Put the cap back on and started and ran the bike with no issue.

Then this morning, engine braking was drastically slowed. Not absent as though I never let off the throttle, but revs dropping very slowly while underway, and then dropping a bit quicker with the clutch pulled in. This makes me think that canister for catching fuel vapor may have something to do with this recent behavior.

If you're talking about the emissions can, these were some of the common complaints I read on older/other models and why it was usually the first thing they removed.

Mine "fell off" during 600 mile service. I fill the way you describe every time.

I wonder if that's what it is that's happening since that first morning's behavior that prompted my first post. I'm going to disconnect it and plug the hoses and see what happens.

UPDATE: Problem solved.

I had all kinds of wonky behavior on the way home from work yesterday. Random refusal to decelerate, blipping throttle would make the revs stay where I blipped them to, having to hit the engine kill switch, even limp mode where a 1/4 turn of throttle and 6000 RPM was the max. I was convinced it had to be the throttle by wire issue and that the only place I'd be riding to this weekend was the dealer. Nope Nope Nope.

I got home and started poking around on the bike. When I tapped the evap canister the tank would vent. I'd hear a Mooooo from the gas cap. The rest of the time it was building so much pressure in the fuel system that there'd be a rush of air when the gas cap was unsealed. Either negative or positive... not sure which, but the fuel system was being heavily impacted by a pressure problem. So this morning I performed a canisterectomy. Then I topped off the the tank and went for a ride.

I am happy to report that after riding the bike for 65 miles that there were no apparent issues with the fueling, in fact it was better than it's ever been... less surging and hunting around than before, much smoother, willing to rev and engine brake as it should. It does however randomly moo when parked. But that's fine. At least its venting.

One small victory.
