The early CBR250R bikes had boggy behavior following a complete closure of the throttle. That should have been corrected by the time that they went to the 286 cc engine, but, maybe the "300 cc" engine had teething problems too. The problem was caused by a too lean injector setting to aid air quality compliance and to aid mpg. CEU reprogramming is one way to solve the problem, using a new fuel map.
