I have had both the Deutz V-8s and now the M11 Cummins, and have a couple of tips: to help keep the aspirators clean, every time I have the air hose in the engine compartment I blow from the top of the aspirator to keep the swirl ports clean(and if I have the outer air cleaner removed, I blow up the bottom of the aspirator similarly), and most importantly, to keep the outer air filter clean longer, I use silicon caulk at the bottom of and all the way around the aspirator below the clamp strap(especially using care to fill the gap at the clamp bolt area!). I did this before last fall, and could run many times longer between cleanings of the outer filter.
