Answer
Hi Damon.
 I don't see anything really awful wrong with this bike, based on what you've told me.

 It probably just needs the carbs synchronized, timing and valves checked/adjusted, possible idlespeed adjustment and MAYBE the manifolds replaced.

 It could also need the carbs reseated in the manifolds and/or the header pipes retightened on the head.  If you see exhaust smoke from the head at the header pipes, then this will be the case.

Any work that needs doing, you should figure into the price of the bike, so keep that in mind.

Good luck.
