The problem with CNC machining a barrel (as opposed to a liner) is the need to leave the transfer port wall (the bit below the port) intact. Itpro will remember the Upton Manx 100cc engines from the 70's, which to allow the prototypes to be machined from solid billets, did not have the transfer wall in the barrel, and this was blamed by many tuners of the day for the difficulties in getting them to go really quick.
