Yes, it's one of Mike's pinions. I have a couple I am testing for him because I really think a solid, consistent mesh is the key to their longevity. Mike just asked me to post my results of this test here. I also have one on my Hyper 8, but haven't run that nearly as much since I'm saving it for race days.

And yeah, there is really no wear. The picture tells the story. I just have to stop using it because of the bore adaptor sleeve. Somehow it must have worn and the pinion wobbles slightly. I did have a time where the grub screw got loose so I suppose the shaft spinning at high speed on a stationary sleeve probably wore it down a little.
