Personally I'd change all the fluids. The oil, and even more importantly the brake fluid, has probably absorbed a lot of moisture from the air, especially that close to the ocean. Also motorcycle oil does more than it does in a car. Besides, lubricating the cylinders, it is also integral in how well the clutch works. IMO it's not that much of a cost for some peace of mind.
Here is a Motorcycle Cruiser magazine article for more information on how a motorcycle clutch works
Or here is a video from Castrol if you don't feel like reading
Also, tires start to have a dry rot concern 5 years after manufacture. I'd have someone who knows what they're looking for check them out to ensure you don't have a problem.
I assume having weekend duty you are a Jar Head or Squid?
EDIT: I see Crossroads already told you to change the fluids and check the tires. I guess I type to slow
But I did add some references too LOL!!!
