Your problem rings a bell with me. I had a 2010 which went onto one cylinder on an Italian Autostrada, and eventually no cylinders. The coils were overheating and failing. It ended up at a Ducati dealer in Piacenza and it took them over a month to eliminate various scenarios, including a bad ECU, but eventually it was tracked down to a short in the loom. In my case there was a tight bend or two in the loom where it runs along the frame and kinks round a bracket or something under the rear of the tank on the LHS, and that's where it shorted out and burned a few of the wires. In my opinion it was an assembly fault on an early bike, but Ducati never admitted anything or helped with the bill despite it being just two weeks out of warranty. So the loom theory could be valid if the timing theory proves negative. Good luck with your odyssey. BTW I think your bike's colour scheme looks great.
Thanks for that insight. It makes perfect sense. Yes a design flaw in the early models wiring loom fits the bill and all the symptoms. That must have been horrible- being on holiday in Italy and having to leave your bike for a month. I’ve never really trusted Italian electronic wiring skills.
Most injectors, including those fitted to Ducatis have a tiny filter in the inlet. They are not mentioned in any service manual nor parts list. The Multi injectors probably have them too.
Btw My Diavel had an intermittent missfire, I used a can of butane and fed raw Gas into the air inlet passage to richen it up and then she ran better but of course it was a little to rich on the other cyl .... but it prooved the point. I used the Oscilloscope to find out which cyl was at fault by looking at the secondary spark wave form, a lean missfire was evident on the H cyl. In the end it was a split in the rubber manifold between the cyl head / throttle body. Breastfed
Now it’s running well with my new Racing ECU But interesting enough when I plugged back in my Rapidbike auto tuner module I got the “injector” error on the dashboard. It seems as if the Rapidbike module is messing up my injector and always on the horizontal cylinder. That was a waste of money! Seems like it blew out my injectors each time I swapped in the new one on the horizontal cylinder. Hence the chasing my tail frustration. Anyone else heard of this problem with Rapid bike modules blowing out injectors?
I wish I had the Pico Automotive scope, I have a Hantek 1008 with a secondary inductive pickup which did the Job perfectly, initially the software was a problem until I found the latest version that would play ball with Win10.
this thread got me out the poop the other day, chasing an intermittent random multiple misfire error. that had been getting progressively worse over a period of wonths on a Renault of all things. there is indeed a filter inside the injectors. I have renewed many injectors over the years because of electrical faults, generally v,easy to diagnose, simple ohms test. but I have never seen a clogged one. let alone 3 out of the 4. I had pumped a few hours over a period of days into this job and I don't charge for failure. then this thread popped into my head on Thursday night. with a few bits and bobs out the way I could pull them out and check the spray pattern. near bugger all out of one. yip, full of grit, one almost completely blocked I. blew them out, cleaned out the rail. put an extra filter in the line as there is supposed to be a lifetime filter in the tank. boom, sweet as a nut and fin takes all the credit. . cheers alex. a wee lesson learned. its so easy to forget the basics once you get a train of thought in your head.
Thx ....have a similar problem with my 2011 1200s touring .... but that happened after a refuel with spilling some fuel over the tank and after 2 km it started tottering, backfiring ,probably 1 cylinder running and than quit totally cleaned the spark plugs etc . but wont start .. going in to deeper now after reading this post
Total last resort stuff but another misfire cause that is easy to overlook and easy not to bother with, as chance of it happening is so remote, not to mention effort involved, and that is water or oil in the vertical cylinder spark plug void.
