Other than the standard tire pressure, brakes, lights,and fork oil only thing I can think of is rear end fluid level. Fill to bottom of filler port with 80-90w gear oil and enjoy the ride. I would probably do a full service since the bike has been sitting for a period. Otherwise your bike is ready to go. I have almost 65k miles on my 06 1100 and do very little to it. If you need a service manual I can email you one that will work.
The part/location that REALLY needs attention (occasionally) on V-Star shaft drives (of all sizes) is the splined hub that is located inside the rear wheel.......NOT the gears in the Rear Axle Gear Case Assembly (sometimes known as the "pumpkin") that is that big silver "differential-looking" thing located at the back end of your drive shaft. The gears inside IT run in a constant bath of 90-weight gear oil and rarely need attention.
It's the "final final" drive gears....(which aren't gears at all, but a pair of splines).....i.e. the "rear hub", which bolts onto the inside of the center of the back wheel and meshes with the "female" splines that are actually on the OUTSIDE of the gear case that usually cause problems and 'go south' due to lack of lubricant.
See illustration from Yamaha parts catalogue, below. It's item #6 that turns to dust if not lubricated.......occasionally! Thank goodness that's the (relatively) cheap part, ($160 in the US....add about a hundred, Canada-side) which I think was designed to be the first-to-fail.....simply because it's easiest to get to.
This particular spot is the one that, by design, is most in danger of being infiltrated by dust, dirt, water etc being thrown up off the rear tire......plus, if you believe many posts here and elsewhere, is for some reason sadly bereft of adequate lube when it leaves the factory.
If you've ever removed your rear wheel......you'll know what I'm talking about. If you've NEVER removed your rear wheel.......it's high time you did. Especially if your bike has over 10K miles on it....or it's time for a new tire. DO have a look at these splines and grease them up well before re-assembly.
