Since i do not own the bike and don't know exactly how it looks (from the images i cant understand much). The only flaw i see is the ram airs when driving in water which would suck water in. Still , in one of your links i read the following sentece: Where is this groove located? Is this hole needed? I mean how can the airbox have extra holes when the intake is from the front. Sorry for my ignorance but as i said i don't have a clear image in my mind yet how the system looks like. Indeed every ram air is kind of weak when driving in heavy rain. I know this from my CBR. I had to drive once in a really heavy rain. The ram air suck so much water which stuck on the filter chocking the engine as there was no air flowing in anymore.
