Guys, a few weeks ago my countershaft bearing failed and took out some tranny parts along with the left side case. I was inspecting everything this afternoon before reassembly and noticed that the kick start idle gear has some uniformed wear on one side of the gear.

Is this done at the factory like this or do I need to replace this gear? See below pics, it's only worn on one side of the gear and it's part #1 on the microfiche. Thanks,Photo

Looks like wear to me. Youd think if yamaha wanted material removed right there theyd do a lot cleaner job than that. That looks like it was chipped away. Not machined. What does the mating gear look like?
