The CarterBrocks are not bad carbs, but their basic design and calibrations are ancient. They really need to be updated. The go-to stock replacement carbs in my opinion are the much newer design and calibration of the Street demons, which are kind of an updated version of the ThermoQuads that replaced the CarterBrock design nearly 50 years ago. I truly believe that the only guys that still recommend the ancient CarterBrocks over the new Street Demons are those who have not tried an SD yet. And without that experience, just how valid is their opinion?
Get the black center version of the 625. They also have a 750, and you could consider that one, but the 625 is probably enough for your application.
