keihin carb question

[u887266]

I have a pair of 40mm Keihin carbs that I am trying to get jetted for my 750sx. The problem I am having is that I found a starting point for my jetting on here but I can not find where to start on my transition jet. My jet right now are 75 low, 135high, and the transition is 45. I dont know if I should leave it or change it, and with way to change it. Any help would be greatly welcomed.

WTH is a transition jet?
I have rebuilt the Keihin on my 750
and it has a low speed and a main jet and that is it

leave it for now, i have been addressing it myself. i was told that we may want to go smaller to lean it out a little at mid throttle if we find that it is loading up during mid thottle cruising.

the 40's off the zxis had the transition jets for sure.

yes this is what the carbs came off of was a ZXI. I will keep everyone one informed on what I find out then.
