ATACC
(Automatic Temperature and Altitude Carburetor Compensator)
This compensator will automatically keep your carbs tuned through all temperatures and elevation changes of up to 8000 feet (2400 meters). The standard compensator is set initially for operation with -20F (-29C) carb jetting for use with snowmobiles, but can be set to use with any jetting temperature. It is also easily set for any operating base (minimum) altitude. This compensator is recommended for the mountain rider who wants to play, not jet.
ATACC is used - but in perfect condition. I have install instructions as well.
If you have a Viper or Viper mountain I also have an airbox and carb cap that have been modified to be able to bolt right in. Seemed to work good - I just didn't need it in my flatlander application.
$130 shipped for the atacc and $170 shipped with the modded viper airbox.
