Mikuni bs34 . Pilot air jet

[David Houston]

Hi guys
I have a pair of mikuni bs34 carbs for my 1977 xs400. Could anyone tell me the diameter of the hole in Air Pilot Jet . I have attached a diagram. On the diagram the air pilot jet is number 53 on the air intake side of the carbs. The Air Pilot Jets were missing when i got the carbs.
Cheers Dave

When rejetting a Mikuni BS34 because of 4 into 1 exhaust and air case channels, ...is the primary and pilot streams the main things to change?? If it's not too much trouble, exhort.
