Pilot jets what difference does the "K" make

[weekendrider]

BS30/96 vs KBS30/96
What if any difference does the K make?
Country of origin?
Different material makeup?
Or has it always been there unknown to me?

The price difference is about half for the KBS ordered from bikebandit
vs. the BS from the dealer or Sudco.

I don't think there's any difference in the part, just the number. Maybe the "K" signifies a "kit" because I see they're selling them in 4 packs. I just got a bunch of jets from here .....

$2.76 each for mains and pilots, free shipping over $40. The good stuff, too, genuine Mikuni.
