    Hi Guys
    Hopefully someone can help me out here.i have pair of Mikuni bs34 carbs on my 1979 yam xs400d. This issues are as following.
    I require 2 x pilot air jets with 6mm
    threads on pilot air jet , i have attached a pic of the air intake side of the carbs, they were missing when i got the carbs.
    I also require 2 x pilot screws for the same carbs. They were siezed when i got them out but the tips were broken off, i have cleanly managed to get the tips out and cleaned the screw passage for the pilot screws. I have also attached a pic of the pilot screw.
    Is there anybody out there can help me find dealers that can supply new pilot air jets and pilot screws 20210503_173404.jpg 20210502_115716.jpg 20210503_173404.jpg 20210502_115716.jpg
