1979 KZ650B Jet sizing

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

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
