Copperhead CDI for 2004-2006 Yamaha Rhino 660. More speed and more power with a functioning speedometer cluster.

FEATURES

- Repetitive fire ignition delivers hotter spark with longer spark duration for maximum power and virtually eliminates misfires, while giving you easy starts and crisp throttle response. Preloaded performance map allows the machine to run cooler, produce more horsepower and more torque, while minimizing fuel consumption.

- Shipped with machine specific harness that plugs directly into factory wiring harness. Toggle switch on the unit allows user to switch between two preloaded setups.

- Default preloaded map keeps factory limiters (reverse / speed) and similar power when the toggle switch is in position #1. When the toggle switch is in position #2, all limiters are disabled, and the timing is optimized for maximum power on 87 octane fuel. Setups and maps can be changed and optimized for different fuel grades via the USB Memory Interface (sold separately).
