Hey Josh...welcome aboard From Christchurch New Zealand...
The 'secondaries' have been removed from the throttle bodies...(not carbs, but thats ok). This was a common thing to do to pre 2014 models to allow the bike to rev as they were restricted in the lower rev range. Since 2014 or maybe even half way thru 2013, these restrictions were lifted so ...
The only thing wrong with that theory is just cos it says its a 2014 or whatever, it dosnt necessarily mean it was manufactured then...only assembled then.You have nothing to worry about there.
You could purchase a "Ramair" filter...(google it)...or triple k&n pod filters.
