This is becoming a common issue as more and more manufacturers have resorted to silicone sealants. Engines are assembled with liquid sealent, the parts torqued down and the bikes shipped. The excess hardened sealant eventually breaks off and finds the oil screen, a process which often continues long after initial break-in, and on occasion to such a degree that it clogs the screen sufficiently to cause catastrophic failure.
China, Thailand and others have increasingly become Japan's "Mexico" with bikes being assembled and/or manufactured offshore for their reduced labor costs. Nightmare stories of entire runs of bikes leaving the assembly line sans oil filters, pickup screens (backward clutch arm springs?) and the like are increasingly common, so it pays to check. Trust not thy dealer, who chargeth for setup, but checketh not.
As the man from N.M. stated, oil is cheap.
