So I can’t get the jetting right on my bike for the life of me.......
Model:2005 crf450x
Air box: cut on top and side
Back fire screen: gone
2006 crf450r head
2002 crf450r CAM
FMF power up needle (clip ring set per instructions for 0-3000 feet)
Current jets 52pilot and 152 main
FMF power bomb header and power core 4 exhaust
O-ring accelerator pump mod
The bike starts and isles but stalls when I hit the gas. Sometimes I can take off and it’s fine once I’m on the gas and moving....... whacking the throttle causes bog or stalling! Any advice!?!? My mind tells me a leaner pilot but I’m lost at this point.
