Hi all--just getting back in after few years and a previous 91 FXRSP with 60k on it. Ran like a top. So bought the FXSTC with 60k on it. Seems to run well. Bit of top end chatter but remember that as a normal thing. How many miles would you expect this engine to have in it? At what point would you expect top end needs rebuilt? And any thing you'd expect as critical consideration at this mileage right away? Thanks!!!
