MSD Yamaha 650 701 Enhancer
The MSD Ignition Enhancer advances the timing of your ski to improve acceleration and throttle response at lower rpm. As the rpm increases, the timing shifts back to factory settings in order to not harm the engine. There is a setting for racers that you can activate for quick and consistent holeshots.
Includes everything needed for installation along with factory connectors for a direct plug-in install.
Not compatible with Yamaha 760 engines.
