@k9forkids actually the 1200 is a 3.5 bore by 3.8 stroke, stock. if you machined out 1/2" it would be a 1560cc/95ci

@import77 Keith Black makes a 3.5" piston for the 1200 which would give you 1380cc so I was told. Take your cylinders to a machine shop that know what are they doing and have them bore out .500" thats right 1/2" over bore. My buddy is doing exactly that!
