Do you know how to remove the tank..? you can see the rear inlet quite easily, it may be possible to do the mod with the air box in place and keep the original clamp's..? Or is there more to the mod than just some lock wire ?
If you want to remove the whole air box you will need a very long cross point screwdriver to reach the front clamp from the offside of the bike through the gap in the frame, you would need a torch and sharp eyes to see the clamp screw .
From memory the offside panel gets in the way a little so you have to move it up slightly.
Once you have loosened the front and rear clamps lift the air box, you will see attached several push fit pipes, an air sensor and underneath to the offside the clean air system is attached, this can be a pain to remove as the screw holding it all to the air box faces downward..
Take note of what you remove with photos and use them as reference on reassembly.
