Looks like the coating is gone on the drive side of the gear teeth. Maybe it's insignificant, but I've never had an issue with the BOP composite gear. Another 1/8" of engagement would be nice.
Do you have a roller cam? Assume that has massaged the cam gear enough?

BTW - mine arrived today!

I have a roller cam.

The whole thing about “smoothing out the cam gear” by running a bronze or steel gear came about roughly 20 years ago. Crane Cams had an issue where the final machining of the cam gear was missed and A LOT of cams were sold with an extremely rough cam gear. It was recommended to run a bronze gear for a couple hundred miles to knock off this roughness and then switch to a composite gear.

“Massaging” the cam gear hasn’t been a “thing” for a long time.

Cliff has stated in the past smoothing the edges of the cam gear with a diamond file. Just tiny swipes off the machined edge from what I recall.
