This is about my CRF50...

Ok, A few days ago I did the "free Mods" I opened up the airbox and cut the screen off the baffle. If runs good everywhere except for when I first Crack the throttle. I can ease into it and it runs great, But when I go from Zero to WFO it wants to fall on its face but then it revs out just fine. I have played with the A/F screw with no luck. If I move the needle will that help??
