Alright, maybe this isn’t for everyone, but I thought it was obscure enough to warrant some interest to any motorcyclist.
What does the AIS do?
“AIS takes clean air from the air box where it is distributed and pulled (under vacuum) past the reed valves and in to the exhaust port where it mixes with
the unburned fuel and ignites @ 1200 degrees it in the exhaust header. ” (quote by 04UpInFlames). Well said.
If you get allot of deceleration popping with a slip on or full system this removed will help reduce it. The AIS helps the bike put out “cleaner” emissions. That’s why a “racer” would have no need for it and if you get a after market pipe some choose to remove it.
Did you get all that?
If you are curious on the details or you actually do have an ’03/’03 Yamaha R6 that needs it’s AIS removed, head to TEZZMIN’s How-to: completely remove AIS post.
