Has anyone completly eliminated bog when you snap the throttle open (0 to 1/2 or 3/4 throttle)? If so, post your jetting setup and altitude. My bike runs perfectly except for the bog when I snap open the throttle to around the 1/2 throttle range. It doesn't happen when I open the throttle a little slower. I'm thinking of going to the E series needle (ERS, EKP) to help eliminate the bog.
