Hi, I m having a problem with a bike, when I am riding and I m off the throttle braking, or going through turn, and then when accelerating again it bogs or does something similar for a while. The engine is not idling, it can be mid or higher rpm when its happening. Can it be caused by mapping or fuel filter? But i dont think its the filter because i have no problem with high rpms, just the on/off transtition. Is it rich?
