All good points above, but I just want to stress NOT to start the engine. Cold starting puts a lot of wear and tear on a motor since oil is not always where it needs to be right away. It also promotes water condensating in the motor oil.
I stored my Wee for over a year - I stabilized the gas and filled the tank, placed it on the centerstand, kept the battery charged, and took the seat off because mice like to nest under it. It started right up after a year+ I ride it regularly now with no problems.
