Sounds like it's going to take a while, certainly more than 30 seconds. I would move on. However if I saw it and was to get it I would do something like come back to shake it with a dog. See if an alarm goes off and if so wait around and see where the owner comes from and how long it takes for him to get there. Then I have an excuse for being near your bike "Hey sorry, my dog got away and bumped into your bike." Maybe stalk it a bit and see when you come and go. It would be out of order for me, but even if an alarm never went off it might be the odd bike I check on the spot. CAREFULLY remove the seats, pull the tank up, look around for wires and boxes that don't belong. Just a quick check for the time being. Get the ignition ready, then start working on the locks and break the steering trying not to move the bike at all.
