What a pain in the rear that was. Anyway, I think I did everything right. I guess I'll find out on the way to work. My chain lasted just over 18k miles. By the looks of things I probably should have changed it out at about 15k miles. I didn't notice the warpage in the rear sproket until I pulled it, but when I looked at it off of the bike, I could see the wear. The front sproket had worn areas on the sides of the sproket instead of the teeth. I think the various noises that I was hearing were coming from the chain not being able to follow the sprokets due to it being stiff in various places. The chain was a mess. It was rusted in numerous links and could have stood by itself.
I thought that each time I was cleaning and lubing the chain and adjusting the slack that things were okay, but there is a night and day difference between the chain I just put on versus the one I just took off.
Photobucket is being slow so I'll post some pics later.
