Not to throw water on your enthusiasm, but in my opinion, a '94 with 65K miles and not running is not a deal even at $2200.
With that corrosion damage you are looking at a tank repair that will require repainting the tank. Even if you do all the work yourself, the materials for a good job will set you back at least $150. The badges alone will cost you over $60.
Then add about $100 for a battery. Install it, and find out the bike has sat long enough to require the injectors to be cleaned. Another $75-100. Have you looked in the tank? If there is corrosion causing a leak, the bike has sat long enough to turn the fuel pump mounting rubber to black goo. If you have to replace the rubber, look at nearly another $100. Then there is also a good chance the fuel pump is toast. OEM is well over $200, and aftermarket pumps can be $75 and up.
How old are the tires? If the bike has sat for a number of years the tires can be over four years old and dangerous to ride on. A set of Shinko Tourmasters, which are the cheapest good quality tires you can find for that bike, will cost you about another $200. For "name brand" tires you can easily go for over $300.
Do the master cylinders leak? A bike that has sat can have corroded cylinder bores in the brake master cylinders(and possibly the calipers) that can cost a lot to repair. Just buying a rear master cylinder rebuild kit can set you back nearly $100. These bikes do not like to be idle for long periods. Long storage might be okay if there are service records showing maintenance during the storage period on time dependent items like brake fluid flushes. Unfortunately, I have never seen a bike stored for a long time that had service of any kind done during the storage period.
Find a jump box to get the engine to turn over, and possibly start. Ask the owner to let you remove the filler and look in the tank with a flashlight. You want to see a nice clean aluminum interior. If it starts and idles and can be revved, the interior of the tank is clean, and the brakes levers have a firm feel, the $2200 price might be fair if everything else is okay.
There are bikes out there in the $2200 price range that are being used daily and don't have the potential issues I have listed above so they can be started up and rode home. A high mileage daily rider is often a better deal than a low mileage bike that has been in the garage for a long time. This is especially true if you are not an experienced wrench and might need to hire out some of the required jobs.
