Today I have something special for you. I have a short post about how to get rid of all that ECO stuff on your bike and make the engine bay a bit less cluttered.

We will be removing the so-called PAIR system. Now what is PAIR system? The PAIR system works by injecting a small amount of air into the exhaust system to help keep the combustion process going. It therefore burns up more of the gasoline that was not previously burned in the combustion process inside the cylinder. It does this via a small air pump that pumps the air into a fitting on top of each valve cover.

What you need for this conversion can be bought straigth from your Kawasaki dealer, as this system wasn’t on the pre 2005 KLE’s those parts are readily available.


Here is what you are going to need:
-2x CAP Part Nr. 110121212
-2x REED VALVE GASKET Part Nr. 110091879
-1x PLUG Part Nr. 920661321
-1x PLUG, RUBBER Part Nr. 92068006

And like with all the things you do on your KLE, you first have to remove the tank.

Here is a picture of the engine bay before removal of the system. Notice that big silver thing in the middle and the hoses attached to it? Those are the things that will be removed.

It is a dirty job, and it will take quite a while to do since you have to remove the engine bars if you are using SW-Motech’s. And you could use someone with small hands as there is a tight fit to plug up the airbox hole.

After some fiddling around and bolting everything back together, this is how it looks all buttoned up.

And what are the benefits of this modifications? Well for starters, there is more room for accessing spark plugs and you get rid of popping out of the exhaust, which is great if you are trying to hide while ridding off road in a country that doesn’t allow it.

Here is what you end up with after removing the PAIR system.

That is it for today, hopefully next week I will have a ride report to post after a whole month of rain.

Stay safe!

    Hi, just wondering what did you do with the hole in the air box? did you close it or change it?
    I know this post is 2 years ago, but I’m following your steps. You did a great job!
