1979 KZ650B Jet sizing

undefined I've recently purchased a KZ650B 1979. It has pod filters, and a 4-1 exhaust.
I believe these are Mikuni Carburetors VM 24SS with accelerator pump

What size Main and pilot jets would you recommend for a setup like this?
Should I purchase Air corrector jets from Zed1015?

I do not have the OEM air box.

Many thanks

Yes, get the air correctors. Have you searched the file base? Type carb jet into the search box of the file base and see what you get.
