    How many CC's is the rear dome larger by?

    Hi,
    Done a search, but can't seem to find the answer.
    On the 1300R, how much bigger volume wise is the rear dome?
    I ask because ive got a set of Riva heads with some ring pitting on the rear one, and I am going to get it mackined out to ease the pressure on the rear cyl.
    thanks.
