Changing the filters is just a case of taking the 3 screws each side out from the air tubes.........accessing the air box, well...............that really needs to be done with the airbox off of the bike ie undoing the clamps on the inlet tubes just prior to the cyl head.
To get it off the bike you need to undo the ign switch mount bolts.....which is easier said than done!
