Not quite an answer to the original question, rather for new parts.
I needed a new breather pipe for the Monster last year as the old one was spilt at the end.
Couldn't be bothered visiting anywhere or calling and trying to describe the part over the phone.
I found 'bike-parts-ducati.com';
https://www.bike-parts-ducati.com/ where I could simply order online from a parts catalogue, price seemed reasonable and it was delivered in a couple of days.
