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.
The AIS Valve Removal kit by SmartMoto combines the electronic AIS valve eliminator with a CNC machined block off plate to let you remove this system from your motorcycle completely.
- 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.
