I paid $4k for my 92 with 17k miles on it. My bike had the head studs replaced prior to purchase because one of them broke.
I disagree somewhat about the carbs. The stock carbs are not super crisp, but that doesn't detract from the bike for me. The flat slide carbs don't have a choke, and can make for difficult starting on cold, damp PNW mornings.
They really are excellent bikes for the $. I go through motorcycles rather quickly. The SS is the only bike that I've ever sold, then bought another one because I missed it so much. Its a keeper. Parts are available and the 2v valve train is relatively inexpensive to maintain. And that sound.....oh hot mamma....that
sound.....
