Hi Ponch, the guy I use in Auckland works on and owns Moto Guzzis, BMWs and assorted British - so a person in that league will possibly have more sympathies with your Morini than an average Japanese repair house. If I take a specific job to him he always gets my manuals and printouts from the clubs or forums to digest over his pre-job tea and biscuits. If it's a problem he has to diagnose, the manuals are vital. The only specific tools I have are an exhaust-nut ring-spanner and the generic flywheel puller many of us have that comes from a Vespa (or similar) dealer.
there are no motorcycle specialists that I am aware of
Oh, and perhaps look harder

spread your net wider, go to any Canberra bike events you can (especially Italian) and talk to people. You'd very likely find someone useful coming out of the woodwork sooner or later. Mate, if I can do it in Auckland ...
Cheers,
Dom
