are you going to ride it at all, the odd hour a week here or there?
Ideally if you are not then filling the tank and adding a fuel stabiliser is a good idea, as is trying to raise the tyres off the ground-front and rear paddock stand, take the wheels off/leave it on jacks.
Oil isn't that much of an issue i *don't* think, unless it due a service very shortly. I would simply change it before you start riding it regular again.
Give it a good clean prior to it being stored away and i would copper ease sliding movements. I would remove the chain and keep it in a tub of oil, if its possible for you to do so.
