Interesting, thanks for sharing.
I will be running these on my next motor and are now feeling a bit uneasy about them.
Just an observation - your adjuster looks too low, the set I have the oil passage to the adjuster is quite high, you need the adjuster down around 1 turn from stopped to line the passage up. But mine have 2 bushes per arm with a void in the middle instead of the groove cut into the bushing like yours so they might have revised the design and moved the oil passage at some point.
