There's been quite a bit of discussion about the airbox mod, how to do it and the effects on the forum recently. so I thought I'd try it and document what I did.
Some people say that it eliminates a high pitched whine and improves the performance and through-flow. Some people say that it screws up their idle speed.
The first step is to get the cover/lid off the airbox - do NOT try to mod it on the bike. You'll either damage the bike or get crap in the engine. This is easy and takes about 5 minutes. On the faired Fazer, you need to remove the four allen bolts on the side of the bike in order to take out the two small bits of inner fairing that hide the gap next to the tank. Then undo the two bolts at the front of the tank holding it into place. Then remove the seat and lift up the tank. I was lazy and just rested it on a bit of rag on the handlebar. You need to unscrew the 6 philips screws holding the top of the airbox on and you can remove it and start cutting!
Here you can see the top of the airbox cover as stock. The hole points towards the front of the bike next to the battery:-
Here you can see the underside of the airbox cover:-
Here you can see the inside of the airbox cover:-
Here is my Dremel that I used to chop bits out. You could probably use a hacksaw but it would take much longer and be much more effort:-
I chopped off the spout thingy on the outside of the cover and also both sides of it that were on the inside:-
Here's a closeup after I smoothed off the edges a bit with a knife:-
Here you can see the inside. There's a lot less plastic there now:-
I left about a cm of the spout in there as I didn't fancy the air blowing straight onto the air filter:-
Nearly done now...
