Used Buying Inspection Checklist

What to look for when buying a used 2016 Harley-Davidson FLHXS Street Glide Special.

Compensator Noise

Listen for a loud 'clunk' or 'bang' during startup, which indicates a worn or failing compensator sprocket, a known Twin Cam weak point.

Infotainment Screen

Check for 'ghost touching' or screen delamination on the 6.5GT unit, especially if the bike was stored outdoors.

Primary Leak

Inspect the bottom of the primary and the inner primary seal for oil weeping, often caused by heat-related seal hardening.

Handlebar Bushings

Check for excessive play in the bars; the stock rubber bushings often soften, leading to a 'mushy' steering feel.
