You didn't say what elevation or temperature you ride in. This will make a difference to the jetting.
Do you do desert riding or more trail riding as you gearing is 12% taller than stock (13/50) and will cut down your acceleration?
Good for cruising desert though, not good for trail/woods riding and will make it harder to lift the front wheel.
What clip position did you use on the new needle? As the clip gets closer to the bottom the richer it will be from 1/4 to 3/4 throttle.
I will take a guess here about your riding conditions at the moment and say you are running rich towards the top end.
I run my needle at the third/middle clip position, there should be 5 cuts into the needle.
I would also drop to the 132 main. I have had to use a 128 main in summer when hot AND humid.
Have you adjusted the fuel screw for a good idle and how many turns out from gently seated is it set.
Once set you can try an extra 1/4 of a turn out to see if them helps off the line, as long as it doesn't foul the plug.
Remember these carbs don't have an accelerator pump.
Alternately some bikes don't like the extra fuelling of the power up setup.
I assume that is different fuel in different countries and the humidity does play its part as well.
Humid weather means your engine sucks a bit less oxygen and needs a bit less fuel.
If you trying dropping the main jet and the clip is right you have an alternative if it doesn't pull middle to top.
If you have a C39A needle as an original it can be paired with a 120 Main for sea level to 1000ft use.
Different elevations may need a different main jet.
I would still use the 45 idle jet at this stage though some went to a 48.
Hope that helps
