zx9r 99 (C model) intake

G'day guys,
just having a look at the bikes intake, under the head light where those air intake slots are, it actually seems to be all closed off and 2 little tubes are what suck in the air.
My question is can u open those slots right up to get more air in? or is it best just leaving it how it is ?
Has anyone attempted it before ? wat results did people get?
Cheers,
Nick
