05 crf450 athena big bore jetting questions

Recommended Posts

I have a 2005 crf 450r with the athena 490 kit, stage 3 hot cam, yoshi header and slip, quick shot, and a uni filter with screen in tact. I ride the mojave desert and tracks mostly around 3500 ft. If you have any jetting suggestions it would be much appreciated..main 180, pilot 48, and not sure on the clip. after reading some old posts I realize that i'm probably going the wrong way. I've got a decel pop.. triple checked timing as well as header pipe connection. all good. the throttle feels like it surges or sticks for a second when rolling to a stop. thanks eddie
