Muzzy Air Shift Kits are the smoothest most efficient kits available. The key to this is the Digi-Kill 3 that kills the fuel delivery instead of the ignition. The result is an amazingly smooth shift that leaves traditional ignition kill shifters in the dust.

These kits contain EVERYTHING you need to add "button" shifting to your motorcycle. Incorporating a high pressure gas bottle, you have up to 800 shifts between fills and that's at least 130 passes down the quarter mile. Unlike other "kits" there is nothing else needed to install and use these kits. All wiring is contained in an OEM quality plug-in loom, and all components are of the highest quality. Your horn button becomes a selectable shift button that easily turns the system on or off and shift kill time is adjustable. Installation is simple and well documented in the full color instructions and there is no drilling or machining required. All mounting brackets are machined from billet aluminum, and all necessary hardware is included. The gas bottle can be filled with CO2, Nitrogen, or Nitrous Oxide at many locations such as welding stores or paint ball centers.

The new ZX-14 Air Shift Kit includes Muzzys' Dual Air/Nitrous wiring harness for a seamless upgrade to the Muzzys ZX-14 Dry Nitrous Kit.

• Digitally matches the kill time to coincide with the actual movement of the shift linkage.
• Momentarily stops fuel delivery instead of killing ignition resulting in a smoother power interruption and less backfiring. (Unlike analog kill boxes)
• Eliminates double shifting due to "button bounce" and always repeats the same sequence regardless of how long the button is held.
• Easily installed on many air-shifted, fuel injected motorcycle.
