I have no idea how many miles are on them. But I installed them yesterday, and it rides and drives like a dream now. I'll get some rear shocks when I see some used on ebay.
Twack helped me install the S-AFC yesterday too. Made a few of those learning mistake, but she's good to go. Really neat how I can look at my throttle position and have a 4 digit rpm gauge.
Now I need a data logger, and I'll have to have her tuned.
EDIT: Here's a pic of the RF spring....could explain why it was hard to steer and made noises all the time:
