To gain access you will need to undo :

The small air feed hose.. 10mm Hex bolt..(like a horn bracket..just swing bracket)

Large feed hose .spring clip (tool required)

2 x 10mm hex bolts.. retaining airbox


Remove all of those and the air filter casing can be lifted free
There is a moulded spike that retains it onto a bracket at rear of engine

Air Filter element



Lay the filter casing on a flat surface and undo all of the Phillips head screws

The filter is then accessible

Check for debris

Install new Filter Element

Replace all Phillips screws.. (get them all half way in..then tighten in sequence )
