The VT-I system includes our special trigger rotor that is designed to be used with the original stock mechanical advance mechanism (not included – supplied by customer). A Hall effect sensor detects the teeth on our special trigger rotor and provides very stable spark timing. A rotary switch is used to set the RPM limiter (200 RPM steps from 5,200 to 7,000 RPM) and a red status LED allows for an easy install.  The  VT-i is compatible with our part number 2005 coil and 3003 wires and most aftermarket dual fire ignition coils (3-5 ohms primary resistance) and has a simple two wire hookup to the coil. Electronic dwell control provides maximum ignition energy at high RPM and reduced current draw at low RPM. The unit operates down to below 6 volts for reliable starting under all conditions, including kick start. The VT-I utilizes fully encapsulated construction with surface mount electronics. The unit is waterproof and highly resistant to vibration and shock. The electronic components include over-temperature protection and are rated to operate up to 125º C (260º F).
