Question, how does it clean up the looks of your bike?
What does this baron's kit do?
I read this on the tech site: Pro on removing the AIS= No more decel popping from your aftermkt exhaust. Is this what you're are talking about?
I have to have it simply put. It's a girl thing...
With the stock pipes, which your looking to go back to, the popping on decel shouldn't be a big issue. If its there, you won't be able to hear it. With after market pipes, its noticeable. The AIS(air injection system)pumps fresh air into the exhaust chambers in the heads, to help com-bust any unburned gas/vapor before it exits the exhaust. The popping, is actually unburned fuel/vapor igniting before it goes racing for the open end of the tail pipe.
The Barons removal kit, simply provides plugs and or covers(depending on the year of bike) to seal the openings in the heads when the AIS fittings are removed. Go down the page to the thread titled "Should I just get rid of my AIS". and on the last page(?), JD posted a link that shows both styles. The plugs for the 99-03, and the bolt on covers for the 04's and laters.
If you look at your bike, on the left side, you'll see a fitting with a hose attached where mine just has a small round mushroom shaped cap. There's one attached to each cylinder. Look between the cooling fines on the front edge of the front cylinder, and the back edge of the rear cylinder and about a third of the way down from the top, you'll see a little button(s)...
The AIS is controlled by vacuum on the older carbed bikes, and electronically on the newer FI bikes. The vacuum activates a switch, that turns the pump on and sends fresh air to the head. It's actually an EPA thingie, whose sole purpose is to convince an exhaust sniffer that any thing coming out the end of the exhaust pipe is as completely burned as possible. Since any residual is being com-busted in the exhaust, it adds no horsepower advantage at all. The exhaust just has more CO1, CO2, and water vapor etc., instead of the more complicated gas vapors from the gas and air mix that may have been there.
