the piston diameter is slightly bigger, thus the slight increase in volume.
means that they need to bore up the cylinders a little.
so its not just going to be a plug and play replacement.
regarding the carb, these CR carbs dont use a vacuum slide which has a slight delay in the reaction time to raise the sliders. when you open the throttle up, it controls the slides directly, giving a more responsive feel.
i believe RacerX is using a CR carb, not sure what size though, maybe the CR31? or one of the bigger ones~
