[british racer]

anybody know how to figure the displacement on a Harley by the cylinder bore? like if its a 1000cc bike and you bore it out say 60 over what would the cc be then? what s the bore on a 1000 cc bike? and a 1200cc bike? thanks

so how much of a bore would it take to go from a 1000 cc to a 1200cc i know theres a cylinder change to just wanted to know the facts
