Brand New 2Fastmoto Honda GL1200 Goldwing Air Cut-Off Valve Kit. The air cut-off valve helps to eliminate backfiring on hard deceleration (throttle fully closed) in constant velocity carburetors. Hard deceleration creates a high vacuum signal in the intake tract which activates the valve. This kit fits into the air cleaner base. Kit replaces 3 Components (diaphragm, spring, o-ring) in Honda OEM Number 16048-MG9-741 / 16048-MG9-671.
