This high quality Japanese air cut off valve kit is a simple but vital component of the carburettor system. Its function is to eliminate backfiring on hard deceleration (throttle fully closed). Hard deceleration creates a high vacuum signal in the intake tract which activates the valve. When activated, it restricts the flow of air to the external idle circuit air jets thereby richening the mixture. This slightly richer mixture is calibrated to eliminate backfiring in this operational mode. If you experience backfiring on deceleration then a faulty carb air cut off valve could be the cause. Please check the image of the kit for suitability before purchase. Suits:

XT600 1987-1989 (Earlier models used a different kit which is also on our website)
