Hi riders, i got a 2016 yz125 with an athena 144cc big bore kit and a after market exhaust setup.

My dirt bike doesn't keep is idle, even if i play with the idle screw (I've tried all the way in, all the way out and every turn in between) I've also play with the air/fuel screw from 1/2 out to 5 turn out and everything in between... it only idle if the choke is on.

Is it possible that i need to change the stock jetting on my dirt bike?? And if yes, what should i buy?

BTW I've also checked for air leaks in the intake boots, and i didn't find any.
