Yes, the vertical cylinder. I have since replaced the Ducati Electronica ignition with a Sachse unit. It still does not idle well on the one cylinder. I am swapping the carbs today to see what effect it makes.
[QUOTE="ArmChairDucati, post: 161858 Hi the Bosch ignition pick ups have very dodgy wires and the insulation can disintegrate causing a short. If you re solder new wires use silicone insulation and leave a fairly long tag of old wire on the sensor and heat shrink it! If you get too close to the sensor the plastic will melt into the copper wire and stop you getting a good join as I found to my cost!! Using too rigid a wire put too much stress on the short piece of wire coming out of the sensor and it sheared off at the sensor - hence the silicone insulation as it is not only oil resistant but more flexible!
