Ah.. then I will talk to the dealer. I kind of CAN'T be without the motorcycle at the moment as that if something comes up in the suburbs, I have to take that job (no car). I'm assuming they take your tank then you have no bike while the new one comes?
Then getting it sealed... do you need to ship it somewhere or is that a home job?
Step 1. Take motorcycle to dealer point out tank is enlarged tell dealer you are having problems re-latching the tank when you lift it for service
Step 2. Dealer orders tank from Ducati - you leave with your bike
Step 3. Dealer calls and says your tank is in 2 to 3 months after step 2
Step 4. Tell Dealer to send it off to get sealed
Step 5. Tank comes back from sealing Dealer calls you
Step 6. Make appointment to get tank swapped - takes a couple of hours
optional step 3.5 you might want to go down to visually inspect new tank - I did turns out these tanks are sitting around in a warehouse somewhere in Italy and not in a de-humidified environment so tank may already have some moisture induced shape changes
Don't wait too long to get the process started turns out Italy shuts down for the month of August
