Welcome to the forum!
+1 on changing timing belts, age alone can cause them to fail.
Unless you know they've been changed recently I'd change all the fluids (Oil, antifreeze, front & rear brake fluid, final drive lube) and inspect the brake pads, at 19,000 miles could be on the "thin" side..
To the left of the battery are three yellow wires going to the alternator stator, look to see if there's a connector on them. This is a known "weak" point in the Goldwing, the connections corrode, the plastic melts and often results in a fried stator. If this hasn't already been done, the best thing to do is cut out the connector and solder the wires directly. Doesn't matter which yellow wire from the stator goes to which yellow wire on the bike.... Call it "preventative" maintenance.
Very low miles on the bike, but front forks may need some service just from sitting, You will need to be the judge of that based on the ride.
You say it runs great. That's good news. Get a can of "Seafoam", use about a 1/4 can in the next four fill-ups, this will help dissolve any varnish from the carburetors.
