Hi Guys
As some of us already know some Ducati models suffer from a cold starting issue. Ducati are well aware of the problem but as now have no idea how to fix it.
I wanted to start a new thread on the subject as I also have this issue and all the post relating to it are outdated now.
So I want to know anyone else that is/has experienced this problem and if you were able to find a resolution or have any information that might help.
From what I have been able to figure out from my hours of google it is most likely down to the "Decompressor"
I found this article that explains it. https://rideapart.com/articles/2016-ducati-959-panigale-ride-review
Basically the part of interest states...
One interesting system bundled into the 959 Panigale is the “Decompressor” engine starting aid. This system modifies cam lift during engine startup in order to keep valves slightly open, reducing combustion chamber compression. This reduces load on the starter motor and battery, in turn reducing the required size of each. This results in an impressive 7.3lbs vehicle mass savings. However, it must be noted that on one occasion, the engine flooded and took several minutes to finally fire up under a cold-start condition. The root cause of this fault was not determined, but it’s hard to ignore the possibility of this decompressor system acting as a contributing factor.
From what I have been able to understand the value stays slightly open to aid with compression but when left for a longer period of time (say overnight) fuel vapours gather and build up though to the air box and that's why it fails to start, this is also why after 1 failed start if you turn the key off for 90 secs it will almost always start on the second hit. Once the bike has successfully started once the bike starts first time every time after that.
So the problem affect all models across the range not just the 959
From my own experience and trying various hit and miss solutions the best I can do is make it start on the 2nd attempt but only if i give it 90 seconds to shut down (you hear a clicking noise after that time)
I have spoken to Ducati numerous times but this problem has been around since Feb 2016 so I hold little hope for Ducati to fix it.
If anyone can offer any insight or better yet has fixed the issue please let me know.
Thanks
