The old style Dynatek two-step rev limiter comes with an adjustable launch rpm setting from 6000 to 8750 rpm in steps of 250 rpm. For a street bike with only a 6 inch over swing arm 6000 rpm could be a little too much so I decided that I had to do something about it. My modifications below extends the launch rpm limit to be adjustable between 4000 rpm to 8750 rpm. $15 for the material, really cheap!
One dual pole switch (6 connectors), used to switch between stock and modified rev limiter.
One 590 ohms 1/8W resistor. One 6.98k ohms 1/8W resistor. One 5k ohms linear potentiometer with a knob.
This is the circuit diagram for the modification, please feel free to e-mail me for any questions, suggestions and/or ideas.
