Cutting Out

elitesoldier357 · Jun 22, 2012

Basically the bikes run a very lean fuel mixture out of the factory to keep them within the emission control regulation requirements to allow the bikes to enter the U.S.

If you dont know what this means it means that your bike sometimes may not get enough fuel into the piston chamber to cause it to fire, therefore cutting out the engine. All I know is you can either have your bike fuel mapped or ECU flashed and richen the mixture, or just wait for it to go away after it is well broke in. Hope this helps.

Strangely enough I had this same thing this week, coming up to a roundabout around 30mph in 2nd, pulled clutch in and it just died. NO spluttering or anything, just cut out with no warning. Coasted to the side of the road and bike started fine, then never happened again.

After removing the carbon canister, mine stopped all the .... .... games.

Fisher1199R · May 30, 2013

My R stalled everytime i came to set of lights if i rolled off the throttle then clucth in BUP stall even if i was rolling in 1st BUP stall Tempramental Bitch she is..... I find giving her little revs keeps her going when coming to stop or down changing for slow traffic.
Everyone looks at me like im a ...... hahahaha

1) CLUTCH-IN EARLIER
2) ENGINE is still tight, be patient.
3) Maybe, adaptive software in engine controller still learning "new virgin points"

At 18,400 miles mine still cuts out. Usually when cold, but not always. Sometimes while the throttle is partially cracked, sometimes 15 seconds after starting the bike while I'm putting on my helmet and gloves (not on the bike, not touching anything).

sounds like a tuning issue to me. it has nothing to do with too little fuel or being lean. that will not kill the bike. an engine will run fine at 18:1 af ratio, not optimal but it will not die. stoich is 14.2 for E10 so 18 is very lean, much leaner than the bike ever sees. max power around 12.8 for E10. in fact, the engine will run with no fuel as long as it is in gear and the rear wheel is spinning.

this sounds more like the electronic equivalent of dashpot.

and there is an electronic throttle control regulating deceleration....we do not have access to it through traditional tuning methods, only fuel and timing maps.

it sounds like this is happening to people that pull the clutch in after accelerating and not to people who are already at idle. it doesn't happen to everyone due to riding style.....

it has not happened to me probably because I let the bike idle down in gear and downshift a lot while slowing so the rpms never drop all the way without assistance.

This post reads as total gibberish....

Im at 1k miles, had the canister removed during first service and the bitch just died on me while stopped at a red light in neutral. Just died. Had to turn key off, turn key back on let it sit for about 20 seconds then fired up, if you don't wait to try and restart after you turn key, it will just putter and sound like a motor with no fuel. ITs pissing me off!

i am not sure if english is your first language, it may not be, I respect that. if it is not, let me know what is and I will repost in your native tongue.

or let me paraphrase for you in even MORE laymans terms:

"this issue does not sounds like a problem with too little fuel as mentioned earlier in the thread."`

if the issue with the post appearing as gibberish to YOU, i suggest you ask yourself if your understanding of engine calibration allows you to properly interpret the post. i hate to break it to you, but it might not.....

furthermore, if the best response you could muster is one analysing my 5:30am-first-sip-of-coffee-grammar, then i can't help but feel sorry for you. anything constructive to add? have you cracked the ecu past the fuel tables giving you something to actually contribute?

Hmmm...Patronising as ever...

But anyway ..you stated engine will run without fuel... I guess as a layman I find that hard to understand... but its an awesome trick...

THAT certainly is a fuel issue.

do you have access to a ducati dealership or a motorcycle technician that can monitor fuel pump voltage, fuel pressure, etc to diagnose the issue? sometimes good old fashioned physical diag is needed. fuel supply or vapor lock is a real possiblity. just throwing stuff out there.

only patronizing to you because you ask for it, nay BEG for it. i think it's funny how far up your thong rides.

yes engines run without fuel all the time. how do you think a bump start works? do you think fuel is injected to start the bike or is it the rear wheel turning the motor over to start the process? like I said, as long as the rear wheel is turning the engine it will continue to run. fuel is only needed for the engine to produce power and overcome the bike/car's inertia. on decel there is no need to overcome inertia, you have momentum. the cylinders are still firing even with no fuel.

cars have Deceleration Fuel Cut Off features that stop fuel injectors on deceleration. Does your car engine turn off when you coast to a stop? no? yet if you measure the AF ratio it will be super lean, as in no fuel lean. they do this for emissions and mpg. look up DFCO.

if the bike dies while stopped at 0 mph and at idle while in neutral like the last guy's bike did then i agree, he is not having a dashpot issue. it could be the tps needs to be recalibrated at 0 or an actual fueling problem. however, not one based in "the map." it is a mechanical/design issue.

Could you please leave the personal attacks at the wayside? We are not a monitored forum, so we have to try to be the adults for ourselves.

As for a bump start, that will not work on an fuel injected engine with a dead battery, unless it has a mechanical fuel pump. An engine will not run without fuel - no spark it can be "dieseling", but fuel is mandatory.

I've been out on my new fishing boat wearing my black rubber suite a lot, catching absolutely no ....... fish!!!

Don't fish understand that when you bring out a fancy new boat they are suppose to bite from my hooks?

Maybe you should have worn your Ducati posing outfit, and they have known you were someone important! Good for you getting off this lusey forum for a bit. You missed the Movie and RSR eras.

Sure, hopefully we all can. If I make a post simply stating certain facts and not directed to anyone I find it uneccesary for any given individual to tell me about his emotional state as a result. Simply put, you and I both know why he posted nothing constructive but instead off topic criticism. It was a thinly veiled passive aggresive personal attack, IMO, and I will respond in accordance, which I am quite certain is exactly what he had in mind. I'll bite every time. No secret there. Or here. Why spend time posting if you have nothing to add to the topic? When I can't comprehend a term or a logic or a concept, I will look it up, not tell the person posting that HE is posting gibberish. lol.

Anyways, I will clarify, an engine will not "run" in the common sense of running, however, it will continue to operate, turn, fire, etc without fuel as long as something is turning the crank, in this case, the wheel. When fuel is introduced it simply gives the spark plug something to light and normal combustion resumes.

And why are we adding factors, like a dead battery?? Last time I checked, no one with this issue has a dead battery...? Did I miss something? DFCO and its principles only work, of course, with a fuel injected engine, which needs an ECM, which of course, needs a battery. If necessary I will state the givens....carburated engines were not able to take advantage of this type of tech.

Thanks for addressing, most of these personal issues can be handled just by calmly discussing.

I was just talking to the point of an engine needing fuel to run, I see your clarification everything else continues with the wheel turning, so engine is "operating" just not "running", waiting for fuel to enter the picture. What area of TX are you in? My family was from Waco/Sherman.

He's easy to find. Just look for the large smug cloud.
