Unofficial, of course. With 15,000 miles on my 2010 Tri-Glide, The Compensator Sprocket just had to be replaced. Luckily problem found at regular service. My H-D mechanic thinks they are making them (and clutch pack for it) out of weak metal. He showed me the wear on it. The owner told him to call The Factory and find out if they have any suggestions for future replacements. It had Screaming Eagle in it and that's what replacement is.
On another note. Ignition Switch replaced for 2nd time. Starter Motor turns on at random times. Not engaging, but still annoying.
Mechanic tells me they are sealed units and made in Mexico. He looked up in the computer and found a massive amount of these replaced under warranty. Doesn't know what The Factory will do in future (certainly not a recall).:blahblah:
