Engine shut down 3rd gear light throttle?!

Hi all,

I took delivery of my V4S last week and absolutely love it!!

Today i took the bike on its first proper ride (around 120km/75Mi). and was riding in quite warm conditions. I noticed once i got caught in traffic and was riding around 70km/h (35MPH) in 3rd gear the bike felt like it shuts down.... When i say that the bike doesn't decelerate, and maintains speed but the bike sounds like its gone silent (relatively) and as soon as you add throttle it barks loudly again with nil issues. At first i thought this was related to the rear cylinder shut down however it only happens in 3rd gear. Apart from the lack of engine noise the bike otherwise feels normal....

I guess my questions are:

-has anyone else experienced this?
-if so is it normal and what is actually happening ie shutting down cylinders or an exhaust valve to make it quiet?
-do ducati have any official information on this if this is indeed a feature?

Look forward to your responses

cheers

Aaron

Good news!!

I went to my local Ducati service centre today and I was told it’s the exhaust valve kicking in (euro 4 emissions crap)

Hopefully there will be an exhaust valve elimination kit released as I like my bike loud 100% of the time

Glad to hear that there's nothing wrong with your bike and surprised that we haven't heard more euro owners complain about this. Suppose these kinds of restrictions have become pretty common.

Really hate that these kinds of regulations have even found their way into premium models. I think it's kind of ridiculous when spending this kind of coin on a bike, to have to turn to aftermarket just to get the proper stock sound.

A few questions for you .... why would you be in third gear in this bike only doing 35mph? I would feel like your very much undershifting this bike ... Second , Can you explain what your experiencing in more detail? Are you loosing power ?? Is the bike acting funny ....

From what I'm understanding, its just a noticeable change in the exhaust note. Looks like EU owners will have to turn to aftermarket for a workaround.

I don’t normally sit in 3rd gear at those speeds but the bike certainly will happily cruise at that speed (4000rpm). I have only done it in heavy traffic when the bike is getting warm.

There is no loss of power, there is no change in engine feel ie vibration etc it only happens on very light throttle (less than 20% throttle, below 5000rpm and only in 3rd gear). The only noticeable thing that happens is the bike virtually becomes silent (very quiet exhaust note) then as soon as throttle is applied or down shift to second gear the bike then ‘barks’ back to life (sound wise) but the bike certainly rides fine in ‘silent’ mode.

I totally agree with the comments regarding the disappointment surrounding the EURO 4 noise crap.... but at least the bike still sounds great for a factory bike outside of this one parameter. They have clearly added this to get around sound/emission laws

Cheers

Alright, so I thought I was lucky and avoided most of the issues with the V4 reported here by others, but I'm around 4700 miles now and in the last 200 miles I've experienced a few things I wish I hadn't.

The DQS stopped working during one ride (did not get the DQS err, but same symptoms, turning the bike off and back on allowed me to use the QS again without issue).

Second, yesterday I noticed power loss while in 3rd (and I think 4th later on, I have to review all my footage).

Here is a short clip, you can hear it at 7 seconds in (I am constant throttle). It happens again (I think it even happened over the bridge, but that could have been bumpy) and I move into the other lane as I thought the thing was going to die completely. Went along for a bit, then it happened again. Got off the highway, turned it off, back on, and I don't think I saw it happen again...

I posted a similar experience, but I was at much lower speed/rpm when it happened. The first thing I did was look back at my back wheel too as it felt like it went flat for a second, just like in that video.

Just to clear up anything, there's no chance your foot covered the shift lever and barely touched it at any of those moments right?
There is always the chance the QS is loose or something and the slightest vibrations starting to set it off? Like if you don't commit to a shift or not accelerating/decelerating and try to shift that would happen where it won't let you shift but tried to start rev matching. Just my thoughts on it not that it is the issue. Of course if it is loose or bad QS, try to get a new one before the warranty runs out

I haven't been able to ride much since I got my new QS 2 days ago but riding home from the dealership it felt better but only time will tell.

I am certainly not on the QS when it is happening. I have about 6 or 7 other videos of it happening and it is definitely the bike surging/stalling. Seems like a fuel/emissions/servo cable issue?

It does buck the bike when it happens especially in repeated fashion like in the video below.

You can hear it happen a bunch of times in that video. Happens even more after I throttle past the car to see if that would fix it. First 10-15 seconds bike is riding fine.

Honestly I thought I was lucky for the first 4500 miles because all I had was the clutch & brake light issue.

Then I experienced all the issues everyone else was talking about (DQS stopped working after 5000 miles randomly, no errors in ECU so dealer doesn't care) along with engine stalling/surging. They were never able to fix the air in the clutch issue even after replacing the slave and master. There's some serious gremlins on this bike--and all the people with sub 4-5k miles are probably in for a treat later on (and either the others with 6k+ are real lucky or have their time coming, even the MCN guy complained about the DQS and he's at 8k).

Yeah I'm at over 6k miles and no issues of those kind... just the not smooth QS which was just replaced couple days ago and clutch fading after recall replaced the clutch kit but they just replaced the pump and seems to be better but haven't had a chance to test it. As for the exhaust servo and such causing it... perhaps? I did have my engine light come on at like 1300 miles for that stupid thing, but can't imagine it would cause your issues but I have no clue if it could or not. As for DQS stop working, maybe it could be some of the sensors on the bike, I've triggered the electronics to throw an error and flash red for just about everything when I had to slam the bike down after a wheelie

Just had to turn the bike off and on to get it to reinitialize though.

I need to find someone local w/ issues on their V4S and swap bikes... see how lucky I really got

Pretty sure you're just as lucky as the rest of us, seeing as you had both clutch and QS issues in addition to also dropping the thing in a garage because of something to do with the kickstand...that club, though.

eh... I guess... but I don't fret w/ things covered under warranty as long as they get fixed "properly" and so far so good. Clutch is finally good and better than when I first bought the bike, and no issues w/ clutch fade after the clutch kit was replaced w/ the recall. Basically the pump had to be replaced and now it works... as intended I guess? But I can now adjust the clutch lever and the friction point is now adjusted accordingly vs original which would start to engage the clutch if you put the screw inwards. So now w/ the adjuster all the way out (screw away from the plunger) it now engages closer to the handle bar and not always way out like before. Adjust the screw inward and engages farther out (how day 1 felt no matter what adjustment was made). And no clutch fade after a day or 2 from the recall (Brembo clutch kit replacement) and requiring me to adjust the lever to compensate and/or pump the clutch lever. Very very happy w/ the clutch fix from Ducati.

The quickshifter, still a little jerky at times at slow accel/decel (maybe there is this learning thing going on, who knows) but going a little hard it's back to being smooth and currently happy with it. And lastly for the drop at the shop, the shop's insurance already cut the check, I decided to go w/ full Ilmberger carbon fiber fairings but going to take couple weeks to get in. New levers arrived today, waiting on mirror block offs and bar end mirrors and bike is good as new

Plus had some money left over and bought a 2016 Ninja 650 from a buddy of mine.
