Now split and fully disassembled, found all the usual....hardened, stuck orings everywhere, nasty insides, way overtightened screws on bowls and tops, ovaled needle jets (unique to Ducati). Small parts in ultrasonic right now, getting a jump ahead.
Owner advises bike (Ducati 900SS/FE) has sat since 2001, wowsers. And he has authorized install of brand new Y-4 needle jets (which I stock specifically for these situations)
