Out goes the hideous, redundant crankase breather hose that ran from the old air box to the black plastic collector beneath the seat, and in comes a small K&N filter. We did consider striping the whole lot back to the crankcase breather, and attaching the filter directly to the breather itself, but to be honest, aesthetically it makes very little difference. Certainly not enough to warrent the risk of oil spitting out onto the rear tyre...that would not be good!
