Description

Air Cut Off Valve Set – XRV750 Africa Twin RD04 (1990 – 92)

This high quality Japanese air cut off valve kit is a simple but vital component of the carburettor system.

• Equivalent to OEM Honda part 16048-MR1-004 (discontinued)

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.

This set contains:

• 2 x Air Cut Off Valve
• 4 x Springs
• 2 x Gaskets
