I hope you are operating the engine longer than that. If you start
the engine, it should be completely warmed up before you shut it down.
Otherwise, you will be putting lots of nasties in the crankcase,
muffler, catalytic converter, etc. The engine should be run until
there is no more moisture coming out of the exhaust. My advice would
be to follow Honda's advice for long-term storage, and leave it alone.
