Any first service that does not include a valve clearance check is incomplete: The valve clearances invariably need to be adjusted from new to broken in. On my V7III Racer, the exhausts had tightened up a little and one intake had loosened up a little. Probably not seriously or with any possibility of damaging anything, but the whole point of a first service post-breaking is to adjust these settings after all the engine and other bike bits have had a reasonable amount of running time in actual service.
