I equally have the problem now because the cable is broken.
Before to bring the bike at the ducati garage (next week) the mechanic asked me what is the behaviour of the engine (power, noise...)
The problem is that finally I can't define if the noise is louder or not. lol
When I turn the key before to start the engine there is not anymore the special noise of the valve movement.
According to the mechanic, the valve is stuck open. So it would signifie that when the engine is off, the valve is open and when we just start it, the valve closing?
Strange? I thought it was the opposite.

Bike went in for annual service last week. Asked Dealer to switch off servo in DDS. Technician advised me that this can only be done on North American models, Australian and European models this function can't be accessed with DDS. So looks like Healtech eliminator for me.

Bringing an older thread up to the front, for those who may not have seen these posts from back in 2019.

It's not uncommon for the exhaust flap mechanism and/or the associated cable to lockup, not only on the SS, but other Ducatis especially if the bike is frequently ridden in wet weather. If it does lockup, an ECU fault will be generated, and it also could be a significant repair bill depending on how locked/damaged the mechanism is.

Some have installed a bypass to keep the exhaust flap open even with the stock exhaust, but for those who have kept the exhaust flap stock, like mine, it helps to do a 5 minute maintenance on it. There is no recommended Ducati maintenance, but I have found checking the valve, and lightly lubricating it every 6 months or so, to be helpful in avoiding a lock-up of the valve, trouble and expense.

Sorry the pics are long gone, but it's a 5 minute job to inspect and lube the flap mechanism and cable. Carefully remove the three screws holding the exhaust flap cover, remove the cover, and inspect that the valve and cable can move freely. Lightly spray some lube on the cable and the join point of the cable with its casing, and also the outside of valve at the rotation points... I use a bit of Silicone / Teflon spray. Put the cover back on with the three screws, and you’re done! I haven’t had any issues with the valve or cable in 4 years of use through all kinds of weather. Just a thought for Members to consider. I just did mine and although everything was moving freely, I put a bit of lubricant to hopefully keep it moving freely.

Thank you Ed,

Just reporting that I did not do any maintenance and I do live in the UK, so have to ride in the rain quite often. So the valve got stuck twice this year with cable snapping up the second time. Repair and cable replacement bill weren't too bad, c£120, but I will start the maintenance bit now and then, especially when it rains. A quick (maybe stupid) question, is it better to lube before, or after a rainy ride? :)

@Timur A Would suggest lubing it when it’s dry for more coverage, before a rainy ride. However, it gets so hot in that area even if it gets wet, it’ll dry very quickly. And the most important I think is to just check it every once in a while to catch it before it starts to freeze up.

Also, this prolly goes without saying, but plz be very careful to not spray some very flammable lube in there when it’s very hot. I wait until it’s completely cool, and apply it sparingly but sufficiently, and work the mechanism by hand to make sure everything is moving properly and not binding.

It’s mostly an inspection and cleaning process when lubing, as prolly a lot of lube burns off. But it only takes about 5 minutes to do the whole procedure.

I was using WD40 gel to service EXUP valve. Recently, I used some Blaster on it. We'll see how that goes.

Ok, on the basis that there is no such thing as a stupid question - can someone post a photo of where the exhaust flap is on the bike?

Everyday is a school day :)

Trip, It's behind the little cover on the right side of the muffler/collector/cat converter. The deal that everyone likes to polish.

It's accessed under cover #9. I think three allen bolts hold it on.

The valve is #19, spray some goop on it.

@Triplesapper Carefully remove the three screws (two are visible in this pic, one is underneath) and the sort of triangular shaped cover for the mechanism, and the flap mechanism and the cable join point, will be visible. Can barely see the black cable in this pic, and where it enters into the cover, with careful viewing.

My bike is still under warranty, the last time that I went to the dealer to have the heated grips installed, the mechanic recommended that I remove the exhaust valve and fit a servo buddy," its only there for ride by noise reduction and they are as useless as tits on a bull". It was the first thing he did when he purchased a new Multistrada. Only cause problems, get rid of it he said, so I did and
I like the improvement.

Yep. My experience too. And the bike sounds better, although it makes it harder for my wife to take off on her ZX14, she can't hear the revs the Kawasaki is making... 😂
