How to: AIS plugging or Removal for better performance

After reading this from jefraider and also AIS removal is part of the yamaha racing in their racing parts for R6/R1,
I'm implementing this on my bike.

For brief description:

AIS means AIR INDUCTION SYSTEM.
Its purpose is to inject fresh air from the airbox going to the exhaust
to burn the wasted fuel thus reducing pollution.

The air induction system (AIS) burns unburned exhaust gases by
injecting fresh air (secondary air) into the exhaust port,
reducing the emission of hydrocarbons.

in short its FOR ENVIRONMENT PURPOSES ONLY :D

if you've noticed on open pipe exhaust, "pop" sounds on throttle release/deceleration
is due to this AIS thing, the burning if wasted fuel is causing that pop sound.

If your an environmentalist, DONT DO THIS.
if your a pro-pollution, follow this , HAHAHA , just kidding.

What we are going to do is plugged the AIS with an object
so that no fresh air will get in.

Heres how to do it.

Materials needed:
-racing slipper (havianas brand preferably, hehehe)
-scissor
-electrical tape



cut a piece of rubber and form it as shown in the picture.



Insert a the plug into the AIS, Insert it in twisting motion


Now put back the hose




Block this small tubing with electrical tape. Just enough the
hose can still be plugin and no air can pass through.




put back the hose



Heres the Final look. Looks nothing is changed.

Enjoy your POPcorn free bike :D

thanks sir traxx!

P.S> hehe, if i go to the emission testing before LTO registration should i pull the plugs out of the AIS to reduce the risk of failing the emission test?

very very informative and helpful tip from the admin...
Lets go race and GREEN!

@2b1ask1... since the process will reduce the emmision of hydrocarbons, you'll definitely pass the test.
