Mikuni carburetor

Let us see the needle. It could be stock or aftermarket so that will change the setting. Do the needles have a Mikuni stamp or Dynojet or Factory Pro stamp?

I understood you. I will see it and write about it later. But I think that it is stock with Mikuni stamp.

Hi again friend! I saw the carb needle and it is 5C42. It is stock needle or no? Why 42 if my carb is BDST38?

5C19-4 for Euro M900 and 900 Supersport and Y-2 needle jet or Factory Pro equivalent.
