hi bradley.
thank you kindly. im sure this will help those going to warranty with this issue.
how many km on your motor btw? production year?
id like to see the response from those who say this noise is normal after listening to your recording and mine / all the others side by side
clearly there is something on motors that exhibit this noise that is maladjusted / misshaped / broken.

Just in case anyone tries to tell you "it's perfectly normal".
The MP3 file is compressed at 192 kbps fixed bitrate, but I only have the (pretty crappy) LAME MP3 encoder, so I provided uncompressed formats if someone needs to do in-depth analysis. The WAV file should play on just about anything. The FLAC file is a "lossless" compressed format.
