hey guys,

just purchased a used FMF powerbomb header for my 02 wr250 along with an.oldschool megamax muffler w/ spark arrestor.

Just wondering what jetting.adjustments need to be made? Bike starts up 3/4 kicks. sometimes pops n shuts off when idling and.then.snapping the throttle. also theres a bottom end bog if I snap the throttle at low rpms.

please let me know what adjustments should be made? all stock bike btw

The system has already.been put on the bike by the way.. I believe its a lean condition

Fine adjust your fuel screw

Increase your idle speed

Service/setup the AP.
