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.
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.
time, air cut off valves will harden up, perforate and/or disintegrate
leaving your bike in a permanently lean, low RPM range (0-2200). When
this occurs, your bike will progressively require excessive choking on
warm-up and will miss during idling, miss and backfire when throttling
up or down, and/or hesitate and backfire when trying to accelerate
quickly. This condition will eventually cause "after burn" generated by a
lean fuel mixture when closing the throttle.
An alternative to purchasing the costly OE assembly is our
inexpensive air cutoff valve kit and, at the same time, replace your
inexpensive carburetor manifold o-rings to insure against any additional
vacuum loss.Click here
