2002 GS500 Rejetting

[Reshef]

Hi guys I read through some threads here and read the wiki page.
I understood that the 2002 Carb has 3 jets and this is what I read here about rejecting but everywhere I check online I see they sell only 2 jets. Main and pilot.

What's the mid-jet? where can I find it?

I didn't see any recommendation for the mid jet of a 2002 GS with stock exhaust but K&N filter. Any recommendation?

Is there a reliable place to buy those jets with international shipping available?

its the same type of jet as main, but smaller.

wiki says 60 or 62.5 i believe
