Thats why I asked for bearing pics, what brand/type bearings? Al based bearings and alot of street type bearing seem to self polish a bit. Any additive in the oil?

I always look for wear consistency off the nose since the lobes were ground from the same blank and it looks like its got it.

Sorry for all the questions, knock on wood but ive always ran solids because they work for me and it would cost alot to switch several motors over to roller and like others, just trying to learn a bit more.

I too had to blow it up to get a better look.
