2011 multistrada 1200s sport injector problem

1A1.gif
 
If you haven't got a clear bag to check the injector spray , you could always use something like an empty water/juice bottle and trim the top off enough to fit the injector in but not enough to spit all over everything. That should give you clear vision and make sure the petrol is re-usable?
 
just swapped the map sensors and the lambadas and it still has the same problem. i disconnected the injector from the boot and it seems to be spraying out fuel ok. i changed the fuel lines around and it seems to be firing better until i pull away and it still wants to die on me until i get it up to 4.500 rpm. could do with a second opinion on the fuel lines. in the workshop manuel it shows the right connector on the fuel tank/pump going to the rear cylinder marked as out, and the left connector as IN going to the front cylinder. hopefully this is correct
 
As I am being somewhat misrepresented in this thread I thought I might provide some background that Ray hasn't mentioned.
I was first contacted by Ray back in April 2020. He had been doing some sort of servicing work on his bike and had managed to break the connector on one of the fuel lines. I pointed out what he needed to replace it and I think he sourced a used fuel line. To fit it he removed the air box and when he put it back together again it was only running on the rear cylinder. I advised the usual checks on sparks and injectors and to make sure that all connectors were fully home. All to no avail. Then he said that a bit of plastic had broken off the airbox and may have gone into the inlet. Obviously, if it had it may have bent a valve so I advised a compression check. At this point I hadn't seen the bike, correspondence was solely by email.
The next I heard was several months later. Ray was bemoaning the fact that Ducati Glasgow had had his bike for months and still hadn't fixed it. They had carried out various diagnostic tests and now wanted to fit a new loom at a cost around £1000. Ray then went on to bad mouth DG, the consequences of which later had serious repercussions, of which Ray is possibly blissfully unaware but which I can't discuss on a public forum. And of course he can't take it back there.
Meanwhile, Ray had removed his bike from Ducati Glasgow and asked if I would check the wiring and repair the loom if necessary. I could find no fault with the wiring between the ECU and any of the injectors or coils. I suggested trying another injector in case the injector itself was the cause and another used injector was sourced. Unfortunately that wasn't the answer.
A few weeks later Ray was bringing his 1098 down in a van for a belt change. At my suggestion he also brought the Multi down in his van, I wanted to do a compression check to make sure that I hadn't missed something obvious. The check showed that the compression was well up to spec. At this point I realised that whatever was going on was not going to be an easy fix and could take a lot time to get to the bottom of, or if I could even find the problem. So had to tell Ray, sorry but there's nothing else I can do.
Since the wiring, injectors and coils all seem to be in order and no fault codes were showing the fault may lie with the ECU itself, and as pointed out by WC Paul 4000rpm is where the closed loop part of the mapping stops. So who knows?

well put and said derek. you just missed out the bit about changing your mind twice. why would i take the bike from inverness to forfar just for a compression test
 
Makes you wonder if the throttle bodies were damaged by the plastic bit
i asked ducati glasgow to remove the front cylinderhead to inspect it for any possible damage just incase the bit of plastic did fall into the inlet/cylinderhead

I thought maybe it got trapped in the butterfly valve and thrown it all out of whack
clutching at straws I know
 
I don't know if this helps on the pipes ?


Ray if I can? Firstly given text often looses context, please accept what follows in a polite and respectfull manner whilst hoping to move things forward (y)

Fuck me, we've all been there. That one bike that absolutely drives you round the bend with a problem that seems impossible to correct but needs to be corrected just so you can get rid of it because enough is enough.

The point of a forum is a group of like minded people to talk bolloxs, have some fun, share opinions and when needed, offer assistance where they can. This isn't however a Ducati dealership or a ducati service centre. We do have some whose life has been a life long Ducati passion where some work with ducati's and they help when they can but most are enthusiastic amatuers.

The range of those, go from one end such as me who apart from being a riding god on the mighty fugly👑 and knows fuck all about maintenance, to those who have an almost biblical experience of fixing and repairing the moody italians most in here ride. The key part on whatever part of the scale you are on however, is the willingness to try and help a fellow forum member out.

Can I say, whilst still being respectfull, that in your written word, you have come across as blunt, argumentative and sometimes confrontational. This maybe due to context, maybe being fed up with the whole thing, maybe feeling let down or a mixture of all of them but, I suspect on occasions, your replies have seen some members afraid to join in the thread which may have seen other options thrown into the pot.

We are a forum of like minded souls and will inevitably offer as you have found, many suggestions to hopefully move a problem forward and as we've seen many of the suggestions offered have helped to eliminate them as the issue.

I hope the diagram above offers some help on the fuel pipes if not, what I normally do is type your model and year of bike and then add "parts microfiche" into the search engine and it gives an awful lot of parts numbers, names and pictures of their position.

I hope you sort it soon chap and the nightmare of your multi can be moved on so you can enjoy biking again. (y)

nearly all the posts have been great, so thanks to you all. but when you get the the same person just posting shite/attention seeking then its a bit annoying

Well, thanks for that apology.... finally.
 
you know who you are , suck me off you ignorant c---. you are the only one that put in threads that were all about yourself and not being helpfull.
I believe this thread has proved that the vast majority of this motorcycles problems are not only caused by its owner's lack of skills / mechanical understanding, but exacerbated by his inability to communicate without insulting.
Now take your toys, put them back into your pram; then take your motorcycle to a Ducati dealer who wants to do the work for you.
You may have to travel a very long way and take an adult to do the talking.
