Hi,
yes marcFX, you are half right , use an alloy air box , but closed at the top and open at the sides ,easy to mount a K&N or Unifilter, Left or Right side access to clean it ,Its a lot easier to get the side covers off compared to removing the seat and seat base,
and on top of airbox, that is, under the seat, safe, clean, tidy, dry mounting for your PVL ignition, it works on mine,
cheers
