1980 kz1000b4 with mikuni carbs HELP PLEASE

so i have the mikuni carbs with pods, and i noticed when i got the bike it would pop and what not like it was running to lean.? lol so i took off the carbs and took out the jets and found one of the pilot jets were broken, so now im trying to figure out what the stock size was and what size these ones are, as i dont know if the bike was rejetted once the pods were put on any help and info would be great.

and so it looks like my pilots are #15 and my mains are 140

Are your carbs the vm or the cv type. Do they have a big round top or a thin narrow top with 3 screws? Also are they 26mm or 28mm (vm) or 36mm (cv)
