i've got a mostly stock 05 450r with only an HRC airbox and a LRD PRO4 slip-on. I just checked the jetting (I bought it used and didn't know what was in the carb) and found a 175 (kehin) main with a 48 pilot jet. The reason I checked is the motor likes to backfire on deceleration. Does this sound normal, or should I bump the pilot to a 50. thanks-oh i live in st. louis for elevation purposes. thanks.
