So I have a friend who is selling his 1980 Kawasaki CSR, It's got 19391 miles on it, and is in pretty good shape. From what I can tell he takes good care of it, with one of the only problems being that the left blinker doesn't work, which he said he'll fix before selling. The Kelley Blue Book for it is $605. Now my question is, would you say this is a fair price for the bike? I know bikes usually have lower mileage because people don't use them as much, however I'm not sure if 19k would be considered a lot. I've seen the checklist recommended and I plan to take it with me next time I go look at it. I've ridden it once already and it feels ok, however this is also my first bike, so I'm not sure what to look for. Any tips would be great, or a recommended offer price.
