I have 12,000 miles on my 08 Fat Boy ridding 'occassionally' on dusty roads/conditions in Vietnam. Drive belt tension has always been proper, yet the chrome in the grooves of the wheel sprocket is worn off. The belt appears to be in good condition for now, layer over all cogs is equal on both sides of the cogs. I am concerned this condition will deteriorate as the sprocket wears out faster without the chrome surface. $200 for a new sprocket + shipping. I guess that is better than replacing both belt & sprocket later. Anyone else have this problem? I have been told somebody anodizes these sprockets for long wear. Anybody know who 'they' are?
