To be sure, you could pull the plugs and put a bit of motor oil in it after you change the oil hot. You want the engine hot to make sure the contaiminats and water go out with the old oil. The new oil will then be clean. I'd also put it on jack stands so you won't have flat spots on the tires. In fact you could change all the goo - brake goo, tranny goo, diff goo, and that would be the best thing for it.
Stabil seems to work pretty good for the fuel, and I have heard fill it up completely to avoid condensation in the fuel tank. On a bike though, I would drain the fuel, and run it until it stalled so everything was completely dry. I'd like to hear some other opinions on that. Many a time I have had to clean a bike carb that gunked up because fuel was left in it, however, when run dry, it was nothing to prime it and drive it away.
Also remove the battery.
On the other hand, if you are going to have someone run it, it'd be best to drive it about for 30 minutes every 2 weeks or so and then you wouldn't have to do anything.
