400ex jetting

I know there’s a billion threads on jetting but I kind of have a unique situation. I jetted my carb for my 426 bore, well I recently switched to a std 85mm bore, best decision ever runs awesome now. But anyways I have a 170 DYNOJET in the main jet and a std 38 pilot ket( I’m irdering a 42, heard great things about it). The air/fuel screw is 3 1/2 turns out. When I hit the throttle really quick, just like a blip it doesn’t respond it just kinda bogs a little. Any suggestions. I have a whole dynojet assortment so any sizes you think are good please tell me.
