...so InnerNerd has a post regarding this but don’t wanna crap on his thread (though the two are related), and I think I know why my Monster is stalling.

It’s definitely happening more and more now with the hot temps in Chicago but the behavior is that the RPM’s dip below 1k when coming to a stop. I can recreate this every single time.

As I’m coming to a stop and I shift down to 1st gear, the RPM will go down to 900-700 rpm’s and the bike will die. No problem, find Neutral and fire her right back up. But why do I have to do this every single time?

The bike is a 2012 796 model with 900 miles on the clock when I bought her. I’ve since put in 160 miles since ownership (yay!).

The bike has termi slip-ons installed by the original owner (unfortunately i’m unable to reach out to him to find out more of the bike’s history) and the stock parts were given to me along with an ECU, which I would assume is stock and a different ECU is in place.

Will this bike benefit from an ECU flash? Is this something a Ducati shop can only perform or will an independent motorcycle shop able to do? I planned a nice, quiet ride this morning but it was cut short (only 5 miles in) due to the stalling and didn’t want to endanger myself in the streets.

Help please! I want to spend more time on the bike rather than it sitting in the garage :(

Hey Belter.

Do you think oil has something to do with this too? I doubt the previous owner performed the first maintenance at 900 miles and I do notice when the motorcycle dies, the oil lights up. Oil looks new but heck, it's a 20 min/30 dollar job so I might as well do that.

Others have pointed out that it could be gas as well. It probably had gas from when it was stored, lord knows how long ago. The stalling happened more when I filled her up (combination of old and now fresh gas) so the advice was to run her till bone dry and fill up fresh.

Thanks again!

Your light comes on when it stalls because the oil pressure drops....thats normal. If it comes on when the bike is running that's when you need to worry.

I doubt it is the gas as well although that is more of a possibility. The bike should idle around 1000 rpm's. My bet is that is the key. IDK if its an ecu issue or something else that controls it such as a valve or vacuum line.

If you want you can try feeding a little throttle in neutral to raise the idle when you are coming to a stop....takes some technique lol . I've used it on a number of Harleys and old beaters before I got them fixed. At least you could ride it some without it dying.

Dude, that's me right now at stop lights - haha! I'm the a-hole that's revving the engine to prevent it from dying. The people around me think otherwise.

I also found a quick idle adjustment process from a different forum and figure give it a try.

Today, it will be oil change, play with idle, and f** * it see if stays up. Thanks to you both so far!

No guarantees that this will help, but it's worked for me in the past on STs that were doing the same thing. Remove the air filter and take a look at the throttle bodies. If you see a black ring around and near the butterflies, wipe it out with a clean cloth soaked with a little carb cleaner. Sometimes that build-up can cause the symptoms you're describing. Good luck!

Just a little tweaking man ....you will get it !! I get the stink eye on my hyper all the time because the clutch is so damn loud and I have a mutt dan moto pipe that is loud as hell.

FWIW I bought a sweet factory service manual on a CD rom from Ebay for 10 bux. It was from England. I bet they have one for your bike. Very handy and covers alot of this type of stuff.

I have not done anything (yet) but here’s a few more observations on the bike.

Neutral idles at between 1300-1400 RPM’s - GREAT!
Coming to a stop (either on Neutral or any Gear), it drops to 1k and below with the clutch squeezed in - DIES!

I initially thought that so long as I am on Neutral then the chances of it dying is slimmer yet it happens too. Oil looks good (will change for sure), but I will also try and empty out the gas tank just by dicking around till it’s time to fill-up.

I’ll perform the other recommendations (air filter) etc. Boooo!!

Oil changed, spark plugs changed (only two, right?), emptied out the gas and put new gas and a touch of sea foam in it....will test ride tomorrow and update the thread!

You think this is the culprit?

It pops a lot too when decelerating. You think that’s an indicator that it’s rich? Thanks for the reply!


makes you wonder if the tps was reset after the new ecu was installed. Get it to a dealer or independent that can set up the fuel injection and see if it is simply needing a re-set. Pplugs are way to black so it is running very rich.

Tps resets every time ignition is turned on so there's no need to worry on that....my plugs are slightly cleaner than that; I've installed a colder plug for a reference but am anxiously waiting a hotter plug....mar8b-jds..if it's stalling because the plug is fouled that might help hotter plug hotter electrode less buildup...mines always run on the rich side too but hasn't stalled coasting since the throttle assembly was replaced...2015 821...was a common problem back then, not necessarily with stalling but the throttle wires were going bad throwing off the signal...spent 6 weeks at a dealer and they never found it even with their diagnostic equipment....striping back some of the insulation from one of the wires would confirm..

That’s interesting. It’s really discouraging when the dealership themselves can’t figure out a problem though that may be my route if the spark plugs do not resolve my issue.

Chase on two wheels I meant snowcat had a similar miserable experience on his hyper821...not sure if the videos are still up but they ended up taking the bike back and getting him a ktm

Quick update

So after emptying out the gas tank, adding fresh gas, putting a bit of sea foam in the tank, and changing the spark plugs - she rides like a dream!

I anticipated a stall on each stop and traffic light I hit, switching from 1st to N and back (I wanted to recreate the stall), RPMS’s remained at a constant 1100-1300. Wow.

I only did errands around the area and put in 10 miles, but I plan on riding some more tomorrow to see if it remains bullet proof.

My baby’s back yo!

Not to be a downer....keep account of the mileage and note when it comes back...new plugs can be like Viagra...your old ones had a definite build up but it did start up hot...the underlying issue still remains, but if clean plugs sort it out then it's a matter of interval ...300 miles than f that...3k miles...weelll could be worse

Most definitely! Probably too early to celebrate and yes, I will keep track if/when this reoccurs. I actually wanted to pull out the new spark plugs (after 10 miles) to see if there was buildup.

Appreciate the input!

What has been removed or added from stock? You have two ecu? I assume the one says racing? If any of the emissions systems were removed check that the lines are in fact plugged or capped...does it idle ok...or will it still stall if given the opportunity...your plug has me thinking a vacuum leak.... definitely running rich...does the bike have an exhaust flap? Is it still connected?

Just took notice that this is a 796...Google tps reset...the 821 does so each time the key is turned on...not sure when Ducati adopted this...might be that easy of a fix

2012, 900 miles, sat in storage for 6 years, termi slipons, and I was given an ECU and most stock parts so assuming it does have the Ducati/racing EUC installed. “DP” also scrolls on the lcd when cranked so I assume that’s Ducati performance?

Worth removing the tank and check all connections to see if something is loose?
