This comprehensive rebuild kit contains all the essential seals, diaphragms, and components required to eliminate vacuum leaks and ensure optimal performance of the emissions control system.

Key Features:

• Complete rebuild kit with all necessary gaskets, O-rings, and diaphragm components

• Precision-engineered components ensure proper fit and reliable sealing
• Restores air cut-off valve operation to factory specifications
• Eliminates backfiring and popping on deceleration caused by worn valve components
• Built to withstand the heat and vibration of high-performance riding conditions

The air cut-off valve (also known as the air injection valve or AIS valve) introduces fresh air into the exhaust system during deceleration to reduce harmful emissions. When internal components wear out, the valve can leak or fail to operate correctly, resulting in annoying popping sounds and decreased performance. This All Balls rebuild kit provides an economical alternative to complete valve replacement, using quality components that meet or exceed OEM specifications.
