I suspect that is probably true...but I also suspect that once the aftermarket and/or Harley catches up and people start really getting into the right combinations of port sizes, fuel pressure regulation, maps, etc. that a well sorted out EFI bike will outrun a well sorted out carb bike. The carb will always be limited by the fact that it is a mechanical devce and operates very simply and one-dimensionally. Simplicity is why lots of people love carbs but that simplicity is also it's limiting factor.HIPPO said:Even so with equal riders the carb bikes will run away from the EFI bikes, stock against stock, not by much, but they will.
