There are two switches for the TORS system. There is one in the throttle lever mounting block and one on the carb rack. At idle, no throttle applied, the switch on the throttle block is open and the switch on the carb rack is closed. As you depress the throttle lever, the switch on the throttle block closes, the slack in the cable is taken up then as the carbs open, the switch on the carb rack opens. The two switches are required to determine if the throttle is working correctly versus a failure. I recently had the TORS switch on my 2003 RX1 fail in which it is open all the time, regardless of pressing and releasing the switch. I confirmed the switch in the throttle block was working correctly. You can access the connections for the throttle block switch under the handlebar pad. You can access the connections to the switch on the carb rack right near the carbs. Check each one with an ohmmeter for operation. If the switches test fine, then the problem is the wiring. Also, be SURE there is enough slack in the throttle cable, about 2 millimeters. The slack is needed to allow the throttle block switch to close before the cable starts moving.
