This is exactly what mine did when the plugs fouled. It was most noticable to me under light to moderate acceleration. Usually when following a slower car down an on-ramp to the highway.
Hang with it. These bikes are quite resilient. You'll come out on the other side. There is a thread around here somewhere about the Fuel Pressure Regulator having some issues and causing 1 or 2 of the 4 plugs to foul.
My fouling problem was a result of a mistake by the previous owner or his repair shop. They accidentally left a hose clamp on the fuel return line that goes from the fuel rail to the tank.
