Not sure if I got you right Yuri. The needle jet setter is different between the stock and the SUGO setup (no emulsions holes in the SUGO setup). Also there is a difference for the needle jet setter between the stock 36mm and 32mm carbs. I'm now looking only for the needle jet itself, still using the stock needle jet setter (with the holes for the main air jet)....
But as the stock 3XV7 parts are not available any more either, I have contacted the local Mikuni distributer. They will check what will fit from other carbs, they thought there will be a good chance, let's see.
