Hey Jimmy,
I've got the 2020 ATAS ES & decided to replace my air filters at 11 000kms.
Only reason why - I had the air filters laying in my tool shed since I bought my Africa Twin.
So I thought, let me see how difficult it is...
I'm not too sure on the standard AT, but on my Adventure Sports, it was a bit of a mission to change.
Okay added, I decided to remove as much of my cosmetics in order to avoid scratching anything.
And removing the airbox covers (taking them out completely) so I could clean everything out (there was some oil from the breather inside the airbox), was also a mission.
I had to loosen my tank & move it back as far as possible just to get the airbox cover to come out.
So all in all - if you want to be fussy like me & clean everything, it is a mission to do. (Unless I just made life unnecessary difficult for myself?)
Compared to my old NC750X this was a hell of a job.
O, and was the old air filters dirty? Not in the least. I actually just waisted my time...
But now I know what a job it is & trust me, I won't be doing that job anytime soon.
