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...

it does afffect the 999's

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

:frog:

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:

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:

burn it :smug:

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:
