I personally would have re-shimmed that 1 intake valve, but I do have the full set of shims in stock.
The factory only uses clear silicone on the valve cover 'eyeballs' on the chain tunnel area. I use None on the KLR's.
But DRZ/KLX400 will leak without silicone on the 'eyeballs'. (I learned that the hard way. Do the job a second time for free.)
The AIS frame nipple may be left totally open. It breathe thru a separate air filter retained by a 4mm allen bolt at the rear end of the frame pipe by the shock mount.
The Black vent hose attached to the air box by the upper shock mount comes from the crankcase, leave it alone.
Be certain that the Evaporative emission hole or elbow just ahead of the RH front corner of the battery in the clean-side of the air box is Plugged!!
That air filter is Perfectly clean on the inside like we knew it should be, because it was well oiled thru & thru. Be certain to re-oil enough to squeeze some back out.
Modify at "YOUR OWN RISK"!
Still riding my 1987 KL650-A1. 85,000+ miles & counting
