Is my sprocket worn out?

I just wanted to post a picture of my old AFAM aluminum 42 against the new identical replacement sprocket. The original sprocket is about 5 years old. Interesting to me: I weighed the old sprocket in it's worn condition and it was 4-1/2 oz. The new AFAM only weighed 4 oz.

My bike sure runs smoother now. I didn't realize how herky-jerky the ride can become if you let your sprocket wear this much. I know I jumped a tooth on one occasion, that was a very unsettling feeling.

I'm not going to say a word about inspecting one's chain and sprockets frequently.
Yep, not a word. Not from me, no siree.

I hope you'll believe me when I tell you I was fully aware of how worn that sprocket was getting. My opening was supposed to be funny/rhetorical. I was being tender to my bikes throttle till I replaced it. I do watch my chain slack very diligently, and as well the rear sprocket. I knew what brand name components I wanted, but had to wait for funds to free up.
It's interesting to me, I couldn't see any wear without measuring, on the steel sprocket up front. That's why I didn't bother taking a picture of it.

Lastly, I'd like to mention Dan Kyle Racing for getting me the best competitive price on the chain and sprocket set, and Barnett clutch set. Mike was totally helpful and patient with my installation questions.
