Hi Jason,
Those plugs in the inner casing are to block the through drilling's that were part of the manufacturing machining
The breather outlet is on the drive side crankcase near the primary case, pointing downwards so not easily visible

The rocker cover breather is non-standard and really shouldn't be necessary.
