the flash of 435 certainly shows NO fuel.
the susvis of 68.6 says its still a 40wt (requires 68.28) if only barely
every thing looks good with 1 exception.
silicon of 20.
that is high for a road bike of only 1000 or 500mi or whatever it was.
its so high that i went and checked my reports...i have just 3 out of 90 that are over 20...on a dirtbike thats raced
in extremly dusty conditions.
so is this leaching from gasket sealers or really sand/dirt past the filter?
you need to look for air leaks.
and if its really from an air leak...we should be seeing more wear metals.
which maybe the lead+tin but yet alum+iron are low.
somethings very fishy about this

Unless you're in a freaking dustbowl, even a filter housing that's not sealed shouldn't let in that much "silicon" in 500 miles in my estimation.
But thanks for explaining there are dual filters, now I can visualize the setup and how the residual oil would be along the edge.
I think you're simply throwing money in the oil analysis if you do another one at 500 more miles. It's really clear there's nothing wrong with the engine, and if everything is sealed up like it should be, it simply is what it is for that silicon reading.
So I took out the filters and upon inspection, one of them, the seal/weatherstripping which goes all around the outside edge of the filter was starting to come apart. In fact, it looked like it had awhile ago because there seemed to be glue residue along the side from previous repair attempts. At the time, I figured I would just glue the portion that had come undone after cleaning the filters. So I made a batch of "maybe a little too strong" simple green and dunked the 1st filter in, and very gently ran my finger across the filter to get any dirt/debrie free and cleaned off. The filter media started to come apart/break free. Time for new filters. Ordered 2 new sets. When I got them, I poured motor oil on them per the owners manual. Then took paper towels and pressed on the media to soak up excess oil. I initially put too much on because when I reinstalled them and started up the bike, it barely ran and died. Took them out, and pressed out more oil, reinstalled, and the bike started right up with a couple black plums of black smoke, most likely from a little bit of residual oil that got sucked out, that was in the airbox getting burned up during combustion.
I'm wondering if that silicon reading might have been from the overall condition of the old air filters that were allowing a little bit of unfiltered air to seep past the filter seals. Either way, I'm glad I replaced the air filters.
