MSD Yamaha 650/701 Enhancer
At lower rpm you'll notice incredible acceleration and throttle response due to advancing the timing. Then as the rpm increases, the timing is retarded to the factory setting to prevent detonation and engine damage. For racers, there is also a lower RPM limit that you can activate for quick and consistent hole shots. Everything you need to install the Yamaha Enhancer is supplied along with factory connectors for a direct plug-in installation!
Not compatible with the Yamaha 760 engine applications.
