If you have stands, put it up on them, if not, make sure air pressure in the tires is to the max sidewall pressure (prevents any flat-spotting on the tires, but for 3-4 months, it's not likely to happen anyway).
Put her away right, and she'll be ready to ride when you get back just like you never missed a beat.
