I’ve heard of plug killing problems like you describe as a result of using Dyna Coils of the wrong output. (Perhaps a reason the CCWs were sold on FB). Are you able to cross check any part number of the CCW coils to ensure they are correct for your model?
while awaiting your next reply - i do remember problems with early Cyclework?Dyna coils that were 3 ohms but still not worth commenting on as you repeatedly return to the front/horizontal cylinder being the problem regardless of which coil (so immaterial overall) but do check impedance ooi. I would stick to the original coils personally as have always been reliable. detailed here also:- https://www.ducati.ms/threads/in-denial-about-ca-cycleworks-coils.734642/
