Great fit and works perfectly
K&S Carburetor Air Cut Off Valve Kit
Direct OEM-style replacement carburetor air cut off valve kit from K&S Technologies. Located on the side of the carburetor, the air cut off valve prevents a lean fuel mixture when decelerating and consequently - backfiring. It works by temporarily closing the pilot jet airway to provide a richer mix as the throttle closes. If your machine has a tendency to backfire, this may be one solution for solving your problem.
- Reduces or prevents backfiring on deceleration
- Includes all required diaphragm(s), spring(s) and/or O-ring(s) as required to service the OEM carburetor

Questions & Answers
Ask QuestionDo I need to purchase 2 of these kits or just 1 for a 1995 Honda Shadow?
By Cody
Answer QuestionIn the case of the Honda Shadows, both the 750 and 1100 cc variants, these kits come with enough parts to service two carburetors. What you see photographed when you select your bike from the fit menu is exactly what you'd get.
Does this kit come with two diaphragms or just one?
By Anon.
Answer QuestionIt depends on what machine you're fitting the kit to. What you see photographed once you select your make, model and year is exactly what you'd receive from your order.
Does this come with two diaphragms or just one?
By Michael
Answer QuestionOnly kits that fit 1997-2003 model year Honda VT1100C Shadow models include two diaphragms. All other kits are shipped with only one diaphragm.
