YZ 125 jetting problem

So we have a 05 YZ 125 we have been trying to figure this problem out for some time now.

 

Bike idles fine, but in low speed low gears it sputters and bogs  REALLY bad. This was happening in all weather

 

Bottom and top end are fresh, reeds are few months on them.

 

took carb off, jets looked clean  running a 410 jet

 

suggestions???
