Ummmm, I personally think that $2K is great price for that bike, esp if it's in good condition. I second what everyone else said about seeing how it runs first.
But if it runs well, I totally agree with LP up there : this site will give you the knowledge, wisdom, and support you need to take care of almost any issues you may come up with. Mine's a 1989, and it had only 7700 when I bought it. Thanks to the great guys (and ladies I think) on this site, I have been able to keep it running top notch.
I did end up replacing the carb assy, but more because the PO broke the entire piece that holds all the idle linkage clean off it - I can't even imagine how.
Personally, I love mine : easy to ride, quick, handles well both in town and on the freeway, looks good, comfortable to ride - need I go on? Lol
If you do get it, be sure to post pics and fill us in on all the details.
Oh, and ride safe
