The best and most reliable stock electronics ignition offered on the market! MSD Enhancer for Yamaha 2-Stroke 650 and 701cc engines (6m6, 61x and 62t electronics).
At lower RPM you will notice incredible acceleration and throttle response due to advancing the timing of the ignition. 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 holeshots.
Everything you need to install the Yamaha enhancer is supplied along with factory connectors for a direct plug-in installation!
*Not compatible with Yamaha 760 64x electronics.
