Any one interested in the oiling mods I did?

the crude 90 degree-drilled-hole-with-sharp-edges could be massaged or otherwise worked to encourage better feed.
That’s what I was thinking. If it is a 90* turn, (and it’s actually a bad thing at 7500+ RPM’s, then, if possible, massage the corners of the passage. IDK. The bigger main feeds can get done this way like Guitar show.

Sorry, more of an observer and reader at this point. I haven’t been there myself.
