I understand, sorry if my post seemed a bit patronising. Things were so much simpler before all this fancy computer fuel injection stuff.
The only other Guzzi dealer I can think of is the Rocket Centre in Blackburn, theyre ok, and will lend you bike. They let me have a Griso overnight as I took my bike in the day before the service so the valves would be cold, then popped back next afternoon when they rang me. 6000 mile service was about £250ish if my memory serves me right.
