BD,
Welcome to the forum!
It shouldn't be too expensive, (although I hear there are a lot of shysters in Florida
) Perhaps not in Dunedin, more around Orlando....
Best check with your local dealer on what they charge, or, have the guy your buying the bike from get it done as part of the deal. Mine cost me $450 AUD, but I really don't know how our prices compare with yours.
In reality, there isn't much to go wrong, but you should check the valve clearances at 12,000, plus they would usually change the plugs, oil, air filters and depending on the weather change the air in the tyres to summer air
