Can anyone tell me what the duct is to the left hand side of the radiator (when looking from the front of the bike)? It has a little bit of sponge at the entrance. Assuming not air intake as it's too small. But then i'm not sure what else air would be sucked in for? Also, is there a way of getting to the sponge and cleaning it, as salt and crap could eventually work it's way in.
