I live in South Africa and am restoring a CB750K1. The bike was a none runner when purchased and came with a set of #064 carbs. These carbs were beyond repair so I found a set of 7A carbs. The 064 carbs have a slide needle with the number 271307 stamped in it. The slide needles from the #7A carbs have the number 27201 stamped in them, What is the correct needle to use in the 7A carbs for my K1 model.
