The oil filter can remove particles that are 5 micron and bigger.
Harley requirement.
Not sure about a requirement. It's just the filter they sell.
I'm sure it's a Super Premium 5 which is rated at 5 micron nominal. There's been great debate about exactly what that means, nominal is usually assumed to be 50%.
Ive cut several including a new one.
Just one example:

OP, Nothing wrong with those results of course.
I see you have 3 samples listed on this report. Sample #2 (18-Jun-24) lists unit time as 26,703 and sample #3’s (17-Aug-24) unit time is 37,892 for a difference of 11,189. The lube time for sample #3 shows 6,030. Did you do an oil change in between?
Since your bike has an M8 motor, are you using either a Harley P/N 62700296 (black) or 62700297(chrome) oil filter?
Most spin on oil filters have some ability to capture some particles down to 5 microns. Since Harley doesn’t list their oil filter efficiency per ISO 4548-12, there is no way of knowing how well they filter. It definitely is not all 5 micron or larger particles.
Also I don’t know why they flag the magnesium at 23-29ppm as high. A lot UOA’s that I see have magnesium anywhere from say 500-800 ppm. The ones that I see that are low like yours is because the calcium is higher.

Yes, there is an oil change in between the last 2 samples.
The chrome one.
I think they flag it based on the numbers given to them from Amsoil?? I had to call Amsoil a while back and ask them why something was getting flagged and Amsoil had them change it at OAI.
Oxi, nice
I also had great UOAs with Amsoil 20w-50.
My engine builder said my internals looked great when he rebuilt my motor.

What were you rebuilding it for? Going to larger displacement, cams, etc.?
Yes I had the engine built, full track build from the crank to the top including porting, Carrillo rods and pistons, cams, upped compression and so it. It saw many years of track use so it was due
