Welcome to the forum!
Looks like it's in good shape for it's age. If it hasn't been running for a while, by all means change the fluids, pull the spark plugs and put some Kroil or the like in the cylinders before trying to start the engine. Also a good time to remove the gas tank (under the driver's seat, I believe), drain, wash out, as well as the fuel lines, so the years of gunk don't haunt you for weeks or months... I learned the hard way.
