How long can reloadable motors be stored?

What if you assemble an RMS motor and the launch is canceled? How do you store it, and for how long?

It is not a good practice to save the motor in this case. If you followed instructions and best practices you used petroleum jelly type grease to assemble the pressure tight inner fittings of your motor. The grease will seep into the fuel grain and contaminate it, causing combustion problems. Pre-building RMS motors, even on the night before a launch, is not recommended. Storing a built RMS motor for as little at 48 hours makes the risk of a CATA or erratic burn too high.

Interesting... the thread has lots of examples where motors were stored for years and worked after! I personally don't build motors until the flight.
