View Full Version : 749r problem
i think im going to give ducati leeds 28 days to sort out the cutting out problem if jhp carnt fix the problem,im awaiting a new ecu from ducati,if the problem is still their:puzzled: im out of ideas,the bike has covered no more than 800 miles from new,the bike has cut out from day one(i put it down to new/tight engine) fed up of not having the bike in my garage for me to ride:flame:,after the 28 days were in to april! i think im going to ask for a replacement, not what i thought i would get for £13,000
pedro when you say cutting out when and how many times is it happening, iv done 3600 miles on my 749r now and have had the bike just cut out when ticking over now and again but it always restarts, its something that used to happen on my 748 aswell so i just really just exepted it but im curious to know how bad yours proplem is?
Have you done any mods to the bike Pedro?

Pedro,mine cut out when new .i found that by leaving the fast idle lever slightly open it cured the problem.
the third new ECU cured it completely .
What tick over speed have you got when the engine is fuuly warmed up?
it cut out when you ie slow down from any speed to a t junction etc.it cuts out also on tick over, but in main its when you down change to lower gears when you roll off the throttle. it does it cold/ warm/ from 20 mph/70 mph. its done this from new in standard form.it has allways had this problem for day one,like i said,i put it down to new engine

Hi My 999 Did it a couple of times just as you said changing down, just cuts out. Warm or cold. It's not the best feeling in the world when it happens (coming into a roundabout with cars up your ass). It must be to do with the ECU as mine dosen't do it now since having the race system with the diffrent ECU. Have you spoke to Ducati UK yet? Hope you get it sorted. Cheers steve

Pedro,
If it's anything like the 749S, it's all to do with cam timing. I had a similar problem on my bike, but it wasn't as severe. It was fixed by setting up the cam timing and tickover again. JHP/Ducati Leeds should know that? Might be worth prompting them though...
Good luck.
most 748R's had that problem, used to really p*ss me off, id be at junctions/lights reving the bike to keep it going. Very cautious when i bought the 996R, this baby runs so sweetly im glad I changed.

my 749 had the same problem an it turned out to be the coils!
These were replaced and has been problem free since, fingers crossed!
jhp on the case now, ducati uk told jhp to do so many things to settings,this hasnt fixed it so its the ecu next,if its not that?..i have faith in jhp to sort it for my track time in spain in 2-3 weeks.
Does it only cut out when it's in gear or doesn't it matter?
There've been a few that have had the clutch dragging. Pull up to a junction in second or first, clutch in and brakes on, but the clutch drags and stalls te motor. Bleeding the clutch has sorted it.
If it cuts out in neutral then please ignore the above and let JHP sort it :bouncy:
cuts out in neutral,rolling with clutch in when changing down ,:(
Forget the bike , do that bloody heating:D

This is definitely a case of "they all do that"
My 748R did it , Mrs eggs 748R did it , my 749R does it...............
My 999S didn't , it would tick over for ever.
I'm told it's a trait of the smaller engine , especially the R's due to the lighter flywheel
Think the 748R's had the issue because of the dual injectors, and when you shut off the extra fuel sits on top of the butterflies until it begins to pour into the barrels, and hasn't vapourised correctly and effectively flood the engine...
Something along those lines, I'd of thought they would have solved this with the 749R though
Yep
deffo a feature of the smaller bore r's from what I have heard and experienced.
Mine still does it if i shut off too quickly or have the revs high and stop. Does it on idle as well, pain in the arse when you are trying to warm it up.
Changing the chip can help and I believe the jhp one is very good for this. I just came to live with it on mine and adjusted riding so its less frequent.
Wow, that sucks. :mad:
Wonder how people just get "used" to that.
Don't give up and make them fix that for good, or go to court if needed.
Why does Ducati sell a bike for that price that just cuts out :puzzled:
And that dangerous too..............
to be fair its not that much of an issue on mine and its never been dangerous, more just a bit annoying when you forget and fly up to a set of lights or something and shut off/barke and it goes. It starts straight away again.
I think its the price you pay for having a very highly engineered and finely tuned bike. As said before if you get the right chip and set up it reduces it considerably.
Not certain if its the same problem here as it sounds a bit often by all accounts so could be all sorts of other things i guess.

I see... but it seems like something all the R's do (you have a 749 R?). I remember reading the 749R presentation to the press and everyone was complaining about it.
And sorry, but it can be very dangerous...... if you're entering a corner, downshift and the bike just cuts of you go like :o:o
Is it only an "R" problem or not?
Ah, and is it exclusive to the 748/749 models or does it extends to the 998/999????
Sorry for asking so many questions guys, but i'm seriously thinking about getting a Duc.

In my limited understanding of the issue it doesn't affect the larger capacity motors. I've never had a problem with my 996 and I've never heard of it affecting a 998 or 999 of any variation.
It is more apparent in the R's --> 749R and 748R
ok, from what i know its only only the 748/749 r models
it was worse on the 748r by all accounts (which is what i have)
It doesn't cut out on corners or such (well mine certaily never has) its when you shut off completly so letting the fuel pool and the sensors cut the engine, nbot something you would do mid corner (neil etc may quote me differently on this).
I don't believ it happens on any of the 996/998 models although when idling i think some bikes may stop anyway...not certain on this, ask one of the others...

All the more reason to get a 996/998 really.

i think the 749/999's just take a bit more setting up. once done correctly then run superbly.

Noooooooooo..... :sniff:
I'm more or less aiming to a 2005 999S :mad:
This has been an on-going problem with my 999r , I've ran the race system and the correct ecu supplied from new. I had the idle increased this weekend but still the bike cuts out after a long blast, or when I'm going to pull away, even though the bike operating temperature.
My bike is booked in for a full set up /dyno run etc.
My worry is that there seems to be a wide spread problem, this leads on to the big question ( a hot topic last week )about fitting power commanders, is this the only answer , or should Ducati be holding their hands up????:flame::flame:

07-Feb-2005, 13:49
mine was pants after having its full sytem fitted, but after being set up correctly and now with a power commander it run perfectly.
ducsoon
i think you have to put it in perspective. There will always be issues with bikes, no matter what make. Ducatis are always highlighted as having problems and being troublesome, but as has been said here once set up right they run great.
Go and buy one you will love it :D
20k and 14k motorcycles , then customer has to splash out another £500 smackers for a power commander and set-up. I love owing the thing only if it would run correctly. I with Pedro on this one , not prepared to push it under the carpet.

As Lilly says , both our 748R's when we had them and my 749R only cut out when standing at traffic lights etc , and only every now and again , it's not as big a deal as some people are trying to make out :puzzled:
I notice someone has posted that their bike cuts out when freewheeling in neutral.........why would you do that ?
i can see me being with-out the bike in march if its not sorted,if jhp dont have any luck with the new ecu,its going back to ducati leeds where i bought it from,i shall set a deadline of 28 days then ask for a replacement, when you pay out £13,000 for a bike it makes you want a 100% working order bike,sounds fair to me?:yawn:
Once at island T/L's
Once at roadworks T/L's
Both times: ticking over nicely, been standing for less than minute at lights, clutch in, first gear, immediate stall. Started again no problem and not happened in last thousand niles, so far so good.
Agree with Green1 though, RSV mille looks decent value. Less servicing cost too.
Pedro
With any luck JHP will get this sorted for you, but out of interest, how often does it do this?
does it stall when you are moving at all, or is it just coming into a stop or when idling? You said its when you downchange? this seems a bit strange.
it cuts when moving,when you close the throttle-change down,it cuts out when tick-over, as for how often,its done under 800 miles so every time i was out running it it.:sniff:
yellowisfriedegg
07-Feb-2005, 15:58
Well if you must insist on a replacement I'm sure Ducati Leeds will swap your nice carbon bodied model for one of the new plastic bodied ones , I'm also sure it will have exactly the same idling problem as ALL 748/9's have ...................alternatively you could always buy a nice little Honda :lol:
when you are actually moving??
so changing down from 5th to 4th for example??
Mine would only cut out when moving if i shut off quickly. Classic was coming into lights or roundabout and not expecting to have to stop so shutting off and grabbing brake whilst trrying to change down quickly. but even so as I was either coming to a standstill or stop it was not an issue as i just hit the start again (don't try dropping the clutch and hoping it will bump - it just ain't gonna happen .. :lol: )
I now ride it differently and have adjusted to shut off more progressively and less sudden and its far better.
it cuts when you slow down from any speed to a stand still,around the 20mph mark when moving with a closed throttle
yep that sounds about right!!
i appreciate you want your bike to run well, but without saying tough luck i think that although the chip should improve things if you shut off or slow down very quickly it can and will continue to do this :(
as i have said I adapted my riding anyway, but it has got noticeable better with age and deffo after running in ( i panicked when it first did it on the way homoe from picking it up!!) I now try to slow down much more and use the gears and it is much less likely to cut out although it still does it on idle at times.
If they cannot sort it your only option maybe to ask them to give you a 999r instead ;)
I hope you get it sorted to your satisfaction :D
My 749 bip has done it two or three times in the 500 miles that Ive ridden it. Again, on closed throttle, clutch in, coming to a set of lights...its not the most confidence inspiring thing to happen. Had to coast to a stop at the side of the road. Wasn't happy at all :(
But it did fire up straight away and my big grin soon returned :lol:

Yep, same symptoms I had on my 749S. It must be the cam timing, same as mine was?

Oh ****!!! 999R's do it too?? :flame: :flame:
Why do you Duc owners unite and actually do something about it???
I mean ACT and make Ducati sort it out at their cost.
One thing is to have a couple of bikes doing that, but when it's a spread issue......... it means there's something fishy there.
it means its a highly tuned engine surely??
i accepted it as although it was a bit disconcerting at first i have adjusted and got used to it and hardly even notice it now. If it was a choice of a Duc with this one small issue or a Honda I know where my money would go....

Yeah Lil, i understand that and it's natural that some bikes (but in a small number) have issues, but when it's something a lot of the same bikes have then it's a serious issue.
The bikes i had so far were all problem free (even my Italian Mille R never gave me a problem).
My current 04 R1 only had a small clutch issue that was fixed with the first oil change.
As for the Duc............ i'm sure i'll love :D it as long as she doesn't have to spend a lot of time in the garage... :puzzled:
I agree it may be the case that its a highly tuned engine, but surely its not THAT highly tuned that we have to suffer cut outs like that?
I'm not complaining too much because its only happened a few times to me, but I agree with DucSoon? that we should get together and demand a solution from Ducati. We've spent a lot of money on their machines, and continue to do so with servicing and parts, I think its only fair that Ducati should provide us with a solution to a problem which seems to be affecting most owners.
Perhaps its a British trait not to complain, I reckon American Ducatisti are getting lawyers ready for a big day in court!

Yeah i know what you're saying........ i don't want a Hon...hon....hon.... unrecognised word :D , but why can't i have a Duc that's problem free??? I'm paying for it ain't i?
the question is is it an issue or a somehwat odd feature?
yes its disconcerting dont get me wrong and i guess it could be an issue if it did it alot as Pedro's seems to be doing. But there are ways to improve this with the chip or the power commander and the rest is down to how you ride.
An example of something similar with a Honda.... the older fireblades were renowned for having serious tank slappers due to the front end wobbling. You could either live with it or buy a damper! the damper improved things no end, but it could still do it if your rode it hard.

Ducsoon - just go get one, you'll love it.
As for Honda - well the SP1/2s haven't exactly got good reputations for fueling!
a couple of mates had 748r's in 03/04 and they both used to die when at a standstill! i remember they always used to be revving their bikes at any traffic lights:lol: sounded nice when we were all out on them:D
Isnt it down to the state of tune of the 748r as it was more supersport homologation special than road bike? i.e. tuned/set-up for racing!!:smug:
my bike has a had terrible flatspot @5k since new, which is so bad that it sometimes feels as though it won't pull through it!:flame: bag o' ****e!!
hoping to have it sort with a new ecu (its at ducati leeds right now) then a pc3 is going on!:smug:
[Edited on 7-2-2005 by chillo]
DucSoon, how many people on here rave about their bike?
How many on other forums rave about their's?
What about say Apple's website, look at the iPod forum...
Everyone complains because someone there might have the answer, I'm not going to ask a question here say about a 1998 Honda Integra Type R with a creeking clutch pedal (common problem BTW), who on here would be able to answer?
So because you see a raft of complaints about Pedro's issues, and then several, and we are talking several people who have had similar problems, you and every non Duke rider might assume is a huge problem. Whereas he is just trying to find a solution on a common forum.

I don't know how common is that problem (but i know it's pretty common unfortunatly, and not just because of what i read here), that's why i asked:
"Is it only an "R" problem or not?

I'm not bashing Ducati, but i think that if a lot of you Duc owners have this same problem, then it's a common Duc issue, and not only i should think twice before i get a Duc but you guys should complain and demand Ducati to fix it.
That's just it.

I just don't buy this argument about the 'R' models being anything special interms of they 'they are race spec road bikes so what do you expect!' Uhhhrrrrm no...its a road bike, thats why it has lights/indicators etc.
To put it into perspective, my 1995 916 SP (with big valves/titanium rods/higher compression/lightweight clutch/lightweight flywheel/big cams/twin injectors) by the sounds of it should be cutting out all over the place, but it ticks over, once warmed, as sweet as a peach (ok its a little lumpy!) and can be ridden like an ER500 if required without having to be revved at the lights or restarted at roundabouts!
If I'd splashed out £13K on a new bike and it kept cutting out on me not only would I be banging on the door of Ducati UK but I would be seriously questioning the safety issues with a bike that can cut out on you when approaching roundabouts/junctions etc.
If it was me I would be seriously miffed:mad:
[Edited on 7-2-2005 by Harv748]
Damn right Harv. Im not bashing Ducati either, I love my bike and thank God they exist, but its a problem that should really be addressed, by Ducati themselves.
Its all good loving your bike and supporting its manufacturer, but blind love is stupid?

as i have said I adapted my riding anyway.
Tough luck ,adapting your riding style are not conclusions, for a serious problem, as stated previously my bike has cut out whilst down shifting approaching a bend at over 80 mph.I,ve ridden different v-twins on the road and under track conditions and never encountered such a frequent cutting out. There must be some technical solution.
Green1
yeah if mine did it at 80 I would be asking questions, but if as pedro says its just when he somes into a halt and when idling its a bit different!
The technical solution is a better chip or a power commander, not certain if there is anything beyond that.
we all accept different things on our bikes and for me its not an issue. I did question it with a ducati expert and i from the explanation I have handled it as best as I could. If it did it to the extent you are saying I would have serious concerns, however i dont think many folks have experienced that.
From what I know the people on here that have experienced it with the 748r (YIFE/Fil2 etc) have never had it to that serious extent.

The point I'm making is I accept a few problems / niggles with such a high performance bike, but with all the testing and static engine development the bike should not cut out with the correct chip and termi provided.
As in previous discussions power commanders should not be an option.
my interpretation of what pedro was saying was if he shut off coming to a standstill, this is a bit different from 80mps on a bend!!
As I said we all handle things differently and we all accept different thing. For me its was a bit odd at first, but adapting my riding and as the bike has aged has meant that I find it acceptable. To someone else it might mean they sell the bike.
Yes, I am sure with engine developments this could be improved and if everyone shouted about this then maybe (just maybe) ducati might do something about it. From what I have read and heard this was mainly an issue on the 748r which in the eyes of the ducati experts that I have spoken to is the most volatile and tempramental of the range due to the extreme level of tuning amongst other more techical things that i can't describe.
Its a shame that Ducati have not resolved this on the 749r, but its pretty unlikely they will go back and resolve anything on a bike no longer being produced (748r).

I wonder how much of this is down to the newer bikes having to meet stringent emission laws? What's the betting it could be 'cured' very easily were the factory able to enrich the mixture without falling foul of the rules. I've a 888 with twin injectors/high-compression/high-lift etc., and I don't have to deal with these 'issues'. Is it mere coincedence that the 888 was built in an era when 'combustion pollution' wasn't such an issue?
Lets all face it... the product is pants really... Just take my R that cost over £20,000 new and has just turned a year old.
3 oil leaks...sorted one of them,back to dealer for others
1 replace fuel tank(peeling lacquer) dont even go there :mad:
fork tube was fitted 180 degrees out from the factory
Having owned 2 R1....1 SP1....1 Busa....1 945 RR with not one drama !

Sure there just on the Ohlins.... so 999S 999R .
What does the mark look like?:puzzled:
and what difference does it make as to where it is? Are you saying it should be at the top for measurement purposes?? and would that make any difference to the measurement??
Andy your bang on....the mark should be up the top like the other fork leg...it makes no difference to measurement...just needs to be tuned 180 in the yoke to match the other fork top.

My 998S was always cutting out in traffic.Great out on the open road,but come into a town and it would cut out.I just got used to blipping the throttle now and again to clear the tubes.:devil:
The 999 has cut out a few times,usually when the engine is very hot and you are pootling.Here's an example,crawling through the gates at Donington after the GP.Or after a hard ride you come into town and the lights take forever to change.Nothing I cant live with.
The bike has never cut out while on the move.:)

My 748R did it a few times when I first had it, set it up with a JHP chip 4.5 to5% co and raised the idle to 1400rpm and its sorted. Just got that bogging left when its been on idle at lights for a while. Powercommander next.
Weve found a lot of Dukes die rolling up to lights and an increase in idle speed sorts it. Almost as if the standard factory idle isnt quite enough with some Dukes.

Chippy had terrible problems with his 749 always failing to idle and cutting out, even after it had been serviced, it was actually worse after having the throttle butterflies synchronised.
The problem was greatly reduced by simply increasing the idle
here is the thread
http://217.199.188.40/xmb/viewthread.php?tid=14414#pid125094
I find it quite amusing to see all this whingeing about cutting out. If you can't cope with a high performance bike's foibles (as in something that is almost a race bike) then you should go get yourselves a nice little commuter. Anything in the state of tune that a 749R or 748R is in will be less than perfectly mannered at low engine speeds... they designed to be ragged..not plodded around on!

This might be complete ******** - but my Carb model 900ss suffered exactly the same symptoms due to carb icing. Is it possible, that a fuel injected Duke can also suffer icing (don't forget that it is the moist air that freezes, not the fuel).
Silkolene Pro FST (Fuel System Treatment) - a kind of anti-freeze worked for me. May be worth a try - about £7 quid a bottle.
its not a ? about copeing with a race bike twpd,the 749r is sold by ducati with indicators,number plate etc for road use,its a road bike,the bike should tick over on its side stand & when coming to a holt.

I can't say what the 748R was like, but what happens on the 749R is not the result of a highly tuned engine, it is a fault. On a bad day it will stall almost every time that you downshift.
Electricsheep did yours cut out when it was standard without all the exhaust and power commander etc ?

Yes it does do it as standard.
My signature is slightly ahead of time. The pipe and power commander go on next saturday. I am hoping that with the custom map the problem will disappear.
What is strange is that it seems to be worse on certain days. I haven't figured out what the pattern is yet.

What exhaust are you running Pedro??
It will be interesting to see if it improves with the new bits on

Having had both 748R and 749R I can tell you the problem is much the same , both mine only ever cut out at tick over , never on down shifts (I don't know what you are doing to make that happen :puzzled: )
I was told by John Tayforth (after sales manager at the time) when I had the 748R that it was partly temperature related and partly because of the lighter flywheel.
Apparently all 748's are more sensetive to mixture / temperature fluctuations and don't like ticking over if the ambient temperature is under 14 degrees (quite often here in Aberdeen) as cold air is denser and affects the fuelling , this combined with the lighter flywheel on the R model results in engine stall at tickover.
The cure , adjust the potentiometers to account for low temperature fuelling fluctuations and increase idle revs slightly , problem gone :sing:

I have a 748RS and it never does it, so I don't think it is due to the state of tune. More likely a design fault or component fault?
Having said that it does idle around 1500+

..but whos paying for all this? When I got my sps it had amajor fuel issue, similar to what is described here. fix it or get it back is my attitude - why do you put up with it??

Ducati must love peolpe like you then, willing to put up with crap product and excuse it so easily! It is sold as a road bike and must fit that purpose.

Not just an r problem maybe
Time for my two penneth!!! (bad spelling)
Had the 749s since jan (03 mod) mine cut out at junctions and stuff but have since learnt that i need to warm it up a bit before i ride of on it (Multistrada went from the word go). So that is not a problem to me
Since today was the first nice warm day out on the bike i decide to give it a handfull (as you do) When the tacho gets to 6 in any gear the bike just dies (not clever on dual cabbageway when trying to overtake) any small throttle openings it is fine till I get to 6.
Well bike going in on Thursday and i have a feeling the ducati warrenty runs out a week or so after.
Thinking the few quid for 2 years extra warrenty was well worth it.
Before any body jumps on me as the previous post, I have gone into this with open mind, love the bike to death and i am sure all will be well:D:D:D:
