I'm happy to report the throttle body intake tubes are clean. I did find the slightest bit of dust in there, but now that this has come to light I will inspect it periodically.
Most all of my riding is in a dry, dusty environment.

So far so good.

Just a bit of residue inside of the lower tube

I have no way of knowing if that was like that before my filter change or not. I lurked on this site for a few months before buying my Talon so I was aware of the stock air filter getting dirty very quickly thanks to guys like
@IDIOT and
@hondabob who changed the intake location with different versions to cleaner air than the stock location. I used the same method as IDIOT to have a pre-filter in cleaner air to supply the airbox. I bought the SYA Warrior Snorkel kit and just put a K&N universal cone filter in place of the SYA's long snorkel. I also put a Filterwears pre-filter screen over the K&N.

This is how my stock Honda air filter looks after the last 400+ miles with the above set up.

This is what the dirty side of the airbox looks like.

I bought my Talon with just over 200 miles on it so the original air filter wasn't pre-filtered the entire time. When I first checked it, it was kind of dirty and I cleaned it a bit then re-installed it right before adding the higher intake with the K&N filter. I had a new filter on hand but wanted to see how the K&N set up worked.
This is about how it looked when I first got my Talon and that's a current picture of it with about 1000 total miles. It didn't get noticeably dirtier but I changed it along with the oils at about 1000 miles.

Running any kind of snorkel kit to get the intake in cleaner air than the stock location of the wheel well will result in much longer service life of the air filter. The channel that the air filter sits in has a rubber foam gasket, and the airbox lid also has the same type of gasket for a positive seal. A new Honda air filter comes with both of those foam gaskets. So unless both of those gaskets were removed from the airbox, I don't know how that much dirt/dust could get past the filter like was shown in the video. Maybe the particle separator was improperly installed, maybe the airbox lid wasn't secured, I don't know. From what I can see it's very difficult to have that much dust getting past a properly installed filter and lid.
