Did you spray starter-fluid down carbs trying to start it? That’s really volatile stuff that will dissolve your rubber diaphragms and O-rings. Luckily, the floppy expanded diaphragm recovered as starter fluid evaporated. Any more and you’ll have holes!
Don’t assume anything! It’s been long time since bike left factory. Someone somewhere in past have tried their hands at “tuning” and gotten things out of whack. Best to clean and restore to 100% factory settings.
And “cleaning” involves more than just spraying “carb cleaner” into carbs. Needs completely disassembly down to last nut, bolt, and individual component. Replace every single seal, O-rings, jets, float valves. Scrub and floss every jet, hole & fuel-circuit. Need soaking in ultrasonic cleaner using caustic radioactive solvents. Finally clean out remnants with micro soda-blasting @ 100000 psi. Measure and adjust float-levels on assembly. Sync carbs and set pilots to 2.5-turns out. Do search here for “clean carbs ducatiman” to see examples and photos of what needs to be done.
