When I read this topic, the keyword is "
needed". Are they "needed"? 'No' is my answer. Are they an advantage? 'Yes'. Is it smoother? 'Can be.' but not always. Does it "rev higher"? Counterweights typically have no affect on how many RPM the engine can rev. The carburetion and induction system generally controls that.
