Description
Backfiring during deceleration is more than just an annoyance—it’s a sign your carburetor isn’t delivering the right fuel mixture when throttle closure occurs. The K&S Technologies Air Cut-Off Valve Set restores proper pilot jet operation, enriching the fuel mixture at the critical moment when your engine is most vulnerable to lean conditions. This direct OEM-style replacement eliminates deceleration backfire and ensures smooth, predictable engine behavior whether you’re tuning a vintage dirt bike or maintaining a classic street machine.
