Community Tip: How-to Completely Remove the Air Induction System on a Yamaha

Fri, 22 May 2009

Alright, maybe this isn’t for everyone, but I thought it was obscure enough to warrant some interest to any motorcyclist.

TEZZMIN, a senior member over at the R6MessageNet forums, has posted a nice How-To on removing an ’03-’04 Yamaha R6 ‘s Air Induction System.

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?

Even if you don’t own a 2003-2004 Yamaha R6, it’s interesting to see how it’s done.  hit the jump for more pics.  Head to the thread to see the details and see the 11 pages of posts that followed.

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.
