Set of 4 high quality slow air cutoff valve kits for 1980 to 1983 GL1100 to replace OEM 16048-443-901 (was 16048-429-771) that 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 GL1100 requires four (4) air cutoff valve kits and this price is for 4 kits. By Barracuda®.
To further insure against any additional vacuum loss, replace your inexpensive carburetor manifold o-rings, 82-610. Vacuum loss can also occur there and mimic the effect of a bad air cut-off valve.
