I'm surprised you guys haven't been hassling Tuneboy -
http://www.tuneboy.com.au/TuneDownloads/Tunes.html - to sort out some tunes for the EFI versions.
I've got a EFI Triumph (not a BA or SM) and it's really simple to upload new maps with the Tuneboy. Initial cost is about £200 ($400) so not cheap. but you'll never have to pay a dealer to upload a new map again - or buy new jets
