    All, Thing to check would be: if the 76cc heads larger chamber footprint [due to larger bore on 472/500] would be wider than the 425 s bore. Dave

      All,
      Thing to check would be: if the 76cc heads' larger chamber footprint
      [due to larger bore on 472/500] would be wider than the 425's bore.
