Anything to worry about with this chain?
I was thoroughly cleaning my chain today, and was noticing that there was grease that kept appearing after it was completely clean. I used WD40 this time, and I'm a little concerned that the grease that appeared is the grease of the internal parts of the rollers. It was black.
After the WD40, I rinsed it up with hot tap water. I think I should be heating the chain before I clean it, but I did not this time. (main reason was that I do not have confidence in putting my bike on the rear stand solo) So my aunt helped me.
Anyway, I took of the sprocket cover to clean the sprocket as well. I could not get to the back side of the exposed areas of the front sprocket, but I cleaned it the best I could.
I noticed the black grease was there after my ride post cleaning. I then wiped off all the black grease, and applied my belray lube moderately, directly on the rear sprocket connection areas.
Another possible issue is the wear on the rear sprocket.
I think this wear actually appeared yesterday, put on a lot of miles, and was so busy thinking about the people i was with that I didn't take a look.
