Hawk 250 boggy carb issue

[Jerrypcman]

Have the aftermarket P30 carb, new bike runs good except when about mid throttle I’ll be riding along and back the throttle a bit to coast/slow down for a second then give it gas again and it Boggs/hesitates then catches back up.

Any idea would be helpful. Running 140/35 jets, clip on second notch up on needle.
