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

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:

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.

Lily 07-Feb-2005 17:08

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....

Spot on Lily.

If you want an easy life go buy Jap.

Go and buy one you will love it :D

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:

khu996 07-Feb-2005 17:16

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?

Lily 07-Feb-2005 17:17

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.

No, no, no, no....... the Duc will make company to the 05 MV F4 1000 :D:D;) (well..... soon enough, i hope)

Steve M 07-Feb-2005 17:20

Ducsoon - just go get one, you'll love it.

As for Honda - well the SP1/2s haven't exactly got good reputations for fueling!

chillo 07-Feb-2005 17:27

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:

JPM 07-Feb-2005 17:31

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?
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."

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.

Harv748 07-Feb-2005 18:00

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:

khu996 07-Feb-2005 18:08

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?

Green1 07-Feb-2005 18:09

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.



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.

Lily 07-Feb-2005 18:14

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.

Lily 07-Feb-2005 18:36

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).

weeveetwin 07-Feb-2005 18:41

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?

dave w 07-Feb-2005 18:46

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 !

The only thing i can say to ducati is... GET YOUR ACT TOGETHER... rant over

:D (still love it really)

Jon 07-Feb-2005 19:05

Dave W, 180 degrees out?

The marks on the top of the forkleg for the preload ....one is set at 12.00 oclock and the other is around 6.00 ish.

Jon 07-Feb-2005 22:46

Are these only on the 999R Dave, or are they on other models with Ohlins forks. Its only that I've never noticed them.

dave w 07-Feb-2005 23:02

Sure there just on the Ohlins.... so 999S 999R .

andyb 07-Feb-2005 23:05

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??

dave w 07-Feb-2005 23:10

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.:)

Mike Davis 14-Feb-2005 22:59

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.

skidlids 14-Feb-2005 23:32

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

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.

pedro 23-Feb-2005 09:04

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.
