I don't have my SV carb notes handy, but I am pretty sure the needle clip goes on the third one down with one spacer on top. The factory Pro and Dynojet kits are almost identical, both needles will work the same as their taper profiles match. You need Mikuni N102/221 main jets for the SV Gen 1 carbs. The size range available covers any size you will need. I have many SV main jets at home. I will check to see what sizes I have and let you know.
