The AIS Valve Removal Kit with Block Off Plates by SmartMoto replaces the secondary air injection system on a motorcycle.

The secondary air injection system (AIS) routes fresh air from the airbox to the exhaust system in order to aid the combustion of unburned fuel in the exhaust. This system is designed to improve emissions on stock exhaust systems, but will cause exhaust popping and backfiring when you fit aftermarket exhausts.

SmartMoto CNC machined parts bring eye-catching block off plates, combined with SmartMoto Complete Sets providing every component you need to eliminate the secondary air system, all in one convenient package.

Key Features

• Eliminates exhaust popping noise on deceleration and backfiring typically associated with aftermarket exhausts.
• Achieves true A/F ratio for fuel tuning. A/F ratio measurements are reliable.
• Free up engine space.
• Can improve throttle response when used with full aftermarket exhaust systems.
• This kit enables you to remove the AIS system completely, including the valve, the AIS covers and the associated tubing.

Note: 

You can verify fitment on your bike by checking under your tank. Installation of this kit is intended for closed circuit competition purposes only. The purchaser of this performance kit acknowledges that it is not intended for street use.
