Airbox mod???

I was checking the downloads section, and cannot find the document regarding the stock airbox mod? Tried searching, but comes up blank. Could someone point me in the right direction, a link or perhaps e-mail? (oops, forgot that Men are not supposed to ask for directions, ) Thanks in advance.

Which air box mod? I don't remember one.

Only thing I recall was drilling more holes into the air box cap's lower portion to allow more air flow. Is this the one?

While on the subject of allowing more air flow into the box; If the retangular plastic piece that sits just towards the front of the Air Box Cap were removed, would that allow more air to enter the air box?

The only airbox mod for the 650's that comes to mind, is the one where the portion of the air filter lid that inserts inside the air filter itself is cut...leaving JUST enough to hold the filter in place.

I did the air box mod R4 speaks of, but I just drilled more holes in the cone of the air filter cap.
I did not see any noticable difference anywhere.

i have seen the things from UNI that you just drill holes in the air box and put these rubber push in things that have foam in them to help filter dirt.
is that what you are speaking of?

I remember reading one about a guy using 1 1/2" pool tubing in his box and deleting the cursed hella hard rubber.

Whoa - I think that's me. I was wondering what you meant when I first saw this thread...

Do you mean these?

I don't think that was you bique, but it looks pretty good. I remember the pool tubing deal.

If I recall correctly, it looked like clear tube with the fiberglass threads in it, and they clamped on the carb intake and were just shoved into the airbox holes, which had to be enlarged a bit. It seemed like a pretty cheap and effective way to get around the hard boot problems we sometimes have.

I found the thread in the archives and the pic is still up! It's called 'boot pain' and a guy named 2fastkawman did it.

I could not get mine to soften at all, used gas trany fluid vasoline ect. even boiling they wouldn't stay soft long enough. Nothing worked so I went to Home Depot and bought 12" of 2" reinforced pool tubing. Heated the ends in boiling water then put it on a bottel with the same size mouth as my carbs and cooled it with cold water. The air box side was just the right size to fit through the holes snugly.
Total cost $2.50 :cool:

Here's the pic

Are those 1.5" Furnco fittings? Did you have to enlarge the two inner airbox holes for it to work? I think I am following this.....you just cut them in half and used the end with the lip on it inside the airbox?
