You can easily adjust the mid adjuster WITHOUT pulling the air box, lifting the tank etc.
Inside the left side of the frame, follow the cable. You'll see it runs thru a zip tie to the frame.
Simply cut that zip tie (the cable isn't going anywhere), disconnect both ends of the cable and you can easily pull the cable
down to access the adjuster. Way easier than lifting the tank, filter, etc.. Makes replacement simpler too..
I cut that cable at least 3 years ago, NEVER had the air box off either...
Just a side note, I have mine adjusted at the top at 3 turns out at the handlebar lever. Just enough to remove the cable for maintainance
