The Haynes manual also agrees.
For the N1 Spectre model

primary main 65
secondary main 90 (2 main jets) and
pilot 35

looks like PO just bumped the 90 to a 122 for the pods. 
Dont use jets from a kit. Proper Keihin jets are not expensive from Z1 Enterprises or JetsRus

Lucky for me I was able to salvage the secondary mains from the other carburetor set I have. So in theory I should have all correct jets with 90-65-35.

Mcdroid mentioned "main air jet Pri.100, Sec.60"

Which jet is that? I don't see it, maybe I'm just missing something haha but if possible I'd like to identify that jet just to make sure I've got the right one.

Thanks a ton everyone for your input 

If someone would like a dynojet kit (I can post a picture of what's there) I'm willing to give it away

Those air jets are pressed into the air intake side of the carb and are not really removable , not that you'd want to remove or drill them on those carbs. Best left alone..

You can see in the following diagram where they are located. The primary main jet is 92063E. The secondary main jet is 92063A through D.

www.partzilla.com/catalog/kawasaki/motor...-n1/carburetor-parts

The letter A-D indicate different jet sizes. The primary main is 65, the secondary is larger.

Hi Texas

Just to avoid any confusion, kz75spectre was asking about the location of the primary and secondary Air jets as opposed to the primary and secondary main jets for which he has posted pics earlier and which are in your partzilla link

Edit
Oops. Apologies. I need to correct myself. The pilot Air jet can be seen at 6 o clock when you look in the intake side with the choke flap horizontal. The Pri and Sec Air jets #s 7 and 8 are internal beneath the diaphragm  and location is shown  in the diagram from the manual below

Thank you all for the input. So from what I understand and for clarity they're not changeable right?
