I had 106000 miles on a 1996 fxd original pullys and belt.Belt still looked fine but pullys you could tell were getting well worn,I traded the bike so who knows how long the belt would have actually went before it snapped.One of the main things to look for is any cuts on outter edge of belt and see if nubs are still solid to rest of belt.if you can move the nubs and theres sighns of it coming it apart it not gona last long.Myself as long as belt looks good I will run it till it snaps
