There are a lot of things to check on a bike that has sat for awhile...
Check all the rubber bits for cracks and such - tires, hoses, fuel lines, manifold rubbers, drain lines, vent line, squirrel condoms, etc.
Check inside that bone dry fuel tank for rust. Also the older TA's had a problem with paint flaking off on the filler neck under the gas cap. - Check that out as well.
Pull the seat and check the air filter and air box for critters or their debris.
Does the previous owner have any maintenance records? That would help too.
Hopefully, you won't find any problems with anything, but if you do - ask.
And welcome - let us know where you are. Someone might be near enough to lend you a hand.
