2004 CRF 450 jetting

Recommended Posts

My bike has a bad backfiring condition on deceleration. It idles well and has no bog when opening the throttle. I have sealed the head pipe to the silencer (PC Ti) and checked the head pipe and carb boots and I have no leak. Do I need to lean out the mixture to get rid of the popping? I currently have the pilot screw 1 1/2 turns out and I run U4 gas. Thanks for any help! 🙂🙂
