Default Throttle Override System (T.O.R.S.) ???????

I've been contemplating moving to a twist throttle however I'm not able to get a straight answer from Motion Pro or Alba on the methodology used to override the TORS system on the YFZ. The thumber has this hooked into the mechanism and the aftermarket Motion Pro twists don't have anything electircal to them.

FROM THE MANUAL:
This model is equipped with a throttle override system as a safety device that operates according ot the positions of the throttle switch and carburetor switch and stops the flow of electricity from the C.D.I. unit to the ignition coil to stop the engine if the carburetor or throttle cable malfunctions during operation.

A- Normally, both the throttle switch and carburetor switch are open when the throttle lever is free and closed when the throttle lever is free.

B- If either the throttle switch or the carburetor switch is closed due to a malfunction, the throttle override system operates to stop the engine.




So my question is for those of you that have converted to a twist throttle.

How have you compensated for this mechanism? and what electrically parts are necessary to move from a thumber to a twist???

Help!

disconnect the the plugs that he wires from the tors on the carb connects into the harnes and then make a complete circuit by connecting the two wires from the harness. There are more sano ways of doing it but it is hard to explain.

are you using the 01 YZ Twist thorttle? what degree rotation is it ?

the motion pro CR for the YFZ calculates to about a 70 degree twist.

I am using an 03 YZ throttle. I dont know what degree it rotates but 70 sounds about right. I hate the 1/4 turns that is why I got this one.
