Sure thing man. It's a dirct bolt on.

1. Remove the factory airbox (big platic box about the size of a happymeal) under the seat.
2. Measure the opening of the rubber inlet hose (I was told you still need to retian the rubber inlet hose)
3. Puchse a cone shaped filter that with an opening that will fit in the hole of the rubber thing.
4. Enjoy more air flow and better performance.

Oh, and you might have to re-jet your carb, depending on how much more air flow you get. I guess you will have to chop the plug to know for sure.

On My KLX I removed the whole air box, filter, carb assembly and replaced it with a keihin FCR41.
Anyway I researced ram pipes and decided I could make a better one.
I did this and fitted it with a pod type filter (flat end with a hole in , no rubber molding).
First test ride and the thing would only do 75mph, came home, took the filter off and went out again, 90mph in the same place, the carb had been sucking the filter in.
I made an aluminium thing to go in the filter and poke through the end and fixed it to the frame with a cable tie, no more filter sucking and I'm a happy chap.
Top speed is limited to about 95 by stability problems but man it gets there fast.

I put on a K&N clamp on pod filter. Works well however it was part of rejetting. I also changed exhaust. I paid alot for K&N then found the filters on the link you posted. I would like to try them if I need to replace the K&N. They are much less expensive.

I removed the whole airbox, moved the battery to the rear and installed a K&N pod filter.  You don't want to forget the crankcase breather, so I installed a breather filter out in the air stream and used the stock hose.  Now I have more room to work on the carb, too.

Hey Greg, hope You still get the chance to open that exhaust port up.

Man Greg, I like your relocation of the battery box.  Did you do away with the side covers, and where'd you put the spark box?  I like your setup alot.

greg, thanks so much for posting pictures of all your hard work.
i am in the process of doing some of the stuff you have already done.
i don't know if i'll move the battery box back though. i am no welder.
right now i am in the process of removing the airbox. it seems to be stuck. i have been trying to remove the belt guard to get at it better(i am thinking there is one more screw to remove behind the guard), but the two screws holding the guard on are stuck tight.
