Now, this isn't a problem, for now anyway. In the first week of ownership, it regularly stalled on closing the throttle, mostly pulling away from idle, but a couple of times while slowing, e.g. coming up to traffic lights, like in 2nd, pull the clutch in to drop to 1st, and the engine dies like you turned the ignition off. However, with the fast idle engaged - because it seemed identical to a carburetted bike with the slide stop too low - the problem has disappeared! The bike has been running well for the past couple of months. The only reason I'm not sure it's solved so much as deferred is there are so many electrical or fuel-based issues that maybe it could actually be (which I just read a couple more of: clutch/sidestand switches). Like I say: it runs well! It's a joy to ride! No more tin box drivers behind honking at me! Initially I was reading about fuel pump relay failures as seemingly inevitable; but the one that still seems compelling is rust clogging the filters (given I'm doing 1000 miles a month, when before it found it's way to me it had only covered 500 in the past 5 years). I daresay it's time to clean the air filters. But, back to the top: it runs great now - and the closed-throttle stalling appears to have been specifically fixed by raising the tickover, rather than by shaking the gas tank. And as I see it, not cleaning the air filters - hypothetically-speaking - will cause it to run rich, waste fuel, and accelerate cylinder wear; but not stall at the lights. So, any thoughts, or advice, will be welcome!
To expand: this is a 'full service history' job, that had just been fettled by Ducati Mumble at little change from a grand.
They do that. As you appear to be in Gloucestershire, I recommend you get it booked in at CJS (same location as Louigi Moto) for one of Chris’ ecu remaps.
Thanks for the suggestion. I've learnt more in 3 days on this forum than in 3 months searching online!
I Had a similar problem on my monster. It was leaks on the connection between the air box and the throttle bodies. If you have an engine stethoscope then may be worth a listen.
The 'engine remaps'. I see Chris w posting a considerable amount of obviously expert advice on using JPDiag (and GuzziDiag) - both of which I downloaded before I bought the bike. I didn't go further at the time as I only have desktop computers. Beyond particular specialist jobs - like having unleaded seats fitted or cylinder reboring - I have always done my own work (I had excellent teachers). Also I build desktop computers, and fix them; so it both galled me, that Ducati apparently expect owners to go to dealers even for basic maintenance, and excited me to discover this software to enable one to turn the nags off: though it never occurred to me for a moment to want to use JPDiag for anything other than turning nags off. Except that, now, I've got the 'maintenance due' icon showing - which seeing as how the bike had the 18,000 mile service before I picked it up, I presume is for something like oil and filter change - but the nag is unobtrusive and I wouldn't even bother turning it off were it not for the fact it seems pretty handy, really, to have the vehicle remind you of this stuff. I also bought all fluids, oil filters, 4 standard plugs and 4 iridium, before I picked the bike up. I had thought I'd get a tablet rather than a lappy, being cheaper, less cumbersome and only for JPDiag and possibly only used one time - but if there are connectivity issues with 'some computers', perhaps a fondleslab wouldn't be such a good idea? Otherwise, apparently, more or less immediately following the demise of the 999 from the range, service intervals were increased. I'm unsure whether it's considered safe to, for example, leave 3000 miles between oil changes on the 999 rather than every 2000. That is I'm unsure whether service intervals were increased because they were a little onerous previously, or because tolerances were made more precise, so don't carry over. And on that subject, the only information I've found to date for service intervals seems to actually be for late-'80s/early-'90s models that don't really seem comparable to water cooled, fuel injected, 8-valve Testastrettas: I would certainly appreciate if anyone could supply me with the definitive 999 service intervals!
