I have a little problem that i can't get sorted out on a 2001 busa. I took my bike to the track and during the first pass it got to breaking up pretty bad. I pulled the plugs to make sure i didn't foul one out. They looked fine except for cylinder #2 so i changed out the whole set. It ran a little better. It will break up and spit and pop around 2500 RMS. If i hold the throttle steady the RMS will fluctuate up and down. And it is also popping back threw # 2 and #3 throttle bodies. I could see the flames up under the butterflies. But it revs fine. And the upper RMS seem fine. I am stumped at the point. Thanks in advance for any and all info.
