you could clamp the petrol pipe then run the bike til the carbs are empty

Yeah, to stop the carbs gumming up, just clamp the pipes, or even shut off the petcock, and run the bike until it cuts out, then try it a few times more...
Other than that, I just top fill the tank, to keep condensation to a minimum, and leave it, but that's with Swedish fuel additives, so might not work for you guys...
Also sort of best done in frost free storage... Plus getting the tires of the ground, and disconnecting or otherwise tending to the battery is a great idea... That's about my whole routine, apart from a sheet over it... It's worked for 10+ years, so I'm not changing it until I need too... (Well, 5+ years perhaps since the other years I've had it in a million pieces...)
