High quality slow air cutoff valve kit, or what Honda refers to as the slow air cutoff valve, for 1984 to 1987 GL1200 that replaces OEM 16048-MG9-741 and 16048-MG9-671. Includes parts necessary for a complete rebuild of the valve (diaphragm, spring and O-ring) so as to improve starting, warm up, idling and acceleration.
NOTE: The GL1200 requires one (1) air cutoff valve kit. This price is for a single kit.
HOW TO IMPROVE START UP, WARM UP, IDLING AND ACCELERATION
To further insure against any additional vacuum loss, replace your inexpensive carburetor manifold o-rings 82-611. Vacuum loss can occur there and mimic the effect of a bad air cut-off valve.
