  2. S = scarico (exhaust)
    A = assunzione (intake)

  6. hopefully my bump will generate more wisdom, but only generalising on previous practice, not just Ducati, the "L" over the "11" is probably related to batch :- i.e. more precisely when created apart from just the year and the "W" is probably to do with combustion chamber configuration, e.g.:- compression ratio/valve sizes.
