Just bought a 2013 HS 821 (Australian version). It has a Termignoni exhaust and an UpMap tune. I have only driven it in warmer weather as it is summer here atm, and every now and then it stalls when decelerating when riding towards a traffic light or a T intersection.
Yesterday the check engine light even came on after I started it again at the T-intersection. When stopped and restarted the check engine light stayed off and had another 2 hours of completely troublesome running.... Weird as.
She can also be hard to start when hot, but not always. So sound familiar to some on here. Any cause or solution identified by you guys?

The revs dropping when the throttle is closed is common. The difficult hot start is often associated with voltage problems due to the imminent failure of the original starter motor. You'll find details in the files but you need to source a decent Denso starter motor that is much higher quality and fitted on later Ducatis. It's a fiddly job requiring the engine casing removal to get at the gears.
Further to your query about the revs dropping, I think I mis-remembered the situation with my HS (I haven't ridden it this winter). I now recall the engine management actually raises the revs just when I'm trying to decelerate. My guru says that happens on a lot of modern Ducatis. Maybe yours needs some tweaking to prevent stalling?
Thanks mate, I will go on the lookout for a new (or second hand) starter!
Will check in with a local workshop with Ducati experience if they can check the stalling issue. Thanks for the confirmation and advice!
