... but look at the picture - this is the other side of the filter![...] Its when you have muck the other side of the filter you want to worry:doh:
As I wrote earlier, the airbox was never previously opened.do you have a breached seal either on the airbox or around the filter ?
Yes, the filter was pre-oiled. Ofcourse, both plastic grilles were fitted.[...] Was it oiled?
Was it sandwiched between two plastic grilles?
Recently opened airbox to exchange stock air filter to DNA and my eyes appeared a terrible view (see photo). :blur:

Hope your bores were sand-free!
Have just removed my airbox again, (to replace my centre coilstick) and have found almost as much sand in mine, but thankfully on the inlet side of the DNA airfilter!
I am amazed that so much sand could get into mine after just 16 kms of sandy track (at very low speed) and gravel road (at moderate speed).
I have removed the flaps and was thinking about re-installing them without the cabling as a sand-deflector/baffle.
A little fine dust got past the DNA filter's edges, so will be adding more grease when I re-install.
There was a lot of dust in the air, especially over the sandy track, but that's what you expect at Australian rallies.
The first tests "on dry" done and the grid does NOT reduce air flow. The only danger that I see is the possible suppression of by the leaves. Solution: do not ride in the autumn :rolling:Note that mesh can be surprisingly restrictive to air flow, even though you can see through them. I wouldn't be surprised if that has almost halved the available inlet area.
I did a similar mod two years ago and it does not affect to the performance. I think is fully recommendable to reduce dust in the air box. About the sand inside the "clean area" of your air box, check carefully the flange of the upper cover, is very short and easy to bend if incorrectly assembled. Due to the airbox design I think is almost impossible that this sand come by the air intake duct but from a point near where you found the dust, like the above mentioned.To go with the punch ... :ele:
i made simple mod:
...and wait for spring to test
