Yeah, day one ais/smog gone, grey wire, throttle stop, air box, jetted, piped. Never looked back, never had to re-jet since, bike rips, why on earth would anyone want to go backwards?

The arguement for putting it back on (at least in California) is the growing awareness among park rangers that 05+ bikes came equipped with it in order to make them meet the the smog/emission requirements to receive a Green Sticker. So, without it they could make your life difficult if they chose to.

do you know besides the restriction what is the performance effect of putting the AIS back?

I removed the AIS but at the same time i did all the WR mods (gray wire, throttle stop, snorkel removal etc.) so i couldn´t feel the perfomance effect of just removing the AIS.

thank´s

We are gonna experiment with leaving it on and putting a single ball bearing int each of the two hoses. Jett it with the proper pilot jett and put in the YZF needle on the four notch, air box mods, replace the throttle stop and remove the grey wire, just like the AIS removal kit instructions tell you to do. The reason is, we can keep the AIS on there for looks but it will perform like we want it to. That way the "Pesky Ranger" wont hassle us. I have friends that did this on their CRF450x's and it worked great.

We all took it off, not because it runs better without it, but because it looks better.

Keep it on or leave it off, it will run the same.
