Is the issue worse in rainy conditions, or cool and damp weather? I find a similar flat spot in my '10 K13GT when rolling on at highway speeds, such as for a pass. Much worse in wet weather, much improved if I replace the air filter at 6k intervals since the filter design on the K13 allows it to pack an unbelievable amount of road-killed bugs around the filter cone in a very short timeframe. The hesitation is at an irritation level, not a problem level, but like you, I suspect I'll be looking at a Booster Plug at a minimum or a remap of the system. In spite of this one small hiccup the bike is an awesome performer and a great ride.
