I am just wondering why do people remove the air box lid on the kdx's? I own one should I take my lid of or not? I have a uni-filter on it.

The reason for removal is simple...improving airflow.  Bike breathes better, it gives more power.

Definitely remove it...the change will be obvious.   You can mount your CDI on the rear fender with a bolt and nut...use loctite on it and you're good to go.

Also, check out  this link for KDX Tech Tips http://justkdx.dirtrider.net/tech_tips.html for all the info you need to wake up your scoot.

I just cut the inside of the lid away removing everything but the 'rim' and the area holding the RECTIFIER(this is not a CDI) :) This way there is no need to 'rig it.

Cheers...

you can drill holes but i found the best performance was to remove it altogether.

Does the removal of the air box lid lean out the bike or make it run richer? Seems mine runs a little richer, is it my imagination?

It sould allow more air which would theoretically make it leaner causing you to need to rejet a little richer. That is the idea anyways and I doubt it made your bike run richer.

I found a 3-step difference in main jet between stock and modified cover.

If you were jetted 'right on' with the stock cover (well, this never truly occured because the vacuum in the airbox made the jetting rpm-dependant), one best change jets to stock baseline or CD's recommendation on JustKDX and resume the jetting process from the beginning after modifying the airbox.
