After a ride, I was rolling my bike, with 5800 miles, into the garage, and I heard a repeating, soft clunking noise for the first time. Sounded like it could be coming from front or rear sprocket area, but favored front. The next day, with cold drive train, no clunking. But after a ride, the clunking was back, but a little worse. Removing the front sprocket cover, the clunk occurred at the same point in each revolution of the front sprocket. The sprocket sort of floats on the output shaft a tiny bit, and I took it off to inspect. The mating teeth were completely devoid of any lubrication, and there was rust beginning on several of the teeth, even though the bike has seen not a drop of water (wash or rain) since I bought it new. I degreased and derusted the sprocket and output shaft, and reassembled with a thin layer of moly lube between the mating splines. Now no more clunking after a ride. Just thought someone might find this useful.
