CV are usually used on street bikes and can fuel very precisely for emissions and have good run quality. The down side is throttle response due to the indirect connection between throttle and carb slide.
FCR, better throttle response and they also use a accelerator pump, which supplys a shot of fuel when the throttle is wacked open. Fuel that the other jets cannot supply fast enough (creating a lean moment). CV carb can also use accerator pumps but it's not too common on most bikes.
