Hi Aaron and welcome to Ninjette!
Worth it....? Depends upon how mechanically skilled you are. There may be many pitfalls awaiting you, based upon past history and maintenance. You may be getting a perfect bike or one that needs thou$ands in repairs.
1. get complete service-records for past 5-years if they're available.
2. take bike and records to reputable shop for pre-purchase inspection. Shop will be able to tell you what service it needs in next year so you can get an idea of what it's going to cost you.
3. check DMV for back-fees which may be due when you transfer ownership.
4. without above, walk away.... from any bike. It's very easy to pick up a money-pit.
Here's some common items that typically is needed, unfortunately, sometimes all at once after you pick up bike. Average shop-prices, can be much less if you can do yourself:
$100 - oil-change & coolant+thermostat. Very first thing I always do.
$200 - fairing-repair and turn-signals. Needs working turn-signals to pass inspection. Also check that brake-lights and horn works.
$200 - tyres, installation & balancing
$200 - brakes, pads, rotors, fluid-replacement and bleeding
$200 - chain & sprockets
$400 - valve-adjustment, the 1988-2007 pre-gen needs this more often than later 2008+ new-get models
$1500 - headgasket repair. Depending upon previous maintenance, you may very well have ticking time-bomb on your hands.
