throttle over ride system, it's the big metal things sitting on top of your carbs.
you can disconnect the control unit to see if it helps,
it's a small black box bolted to the frame just in front of the gas tank on the left side.
it has one wire coming out of it that joins into the wiring loom via one white plug.
there is also a wire coming from the clutch perch which activates the tors when the parking brake is engaged. i can't remember how to disconnect this because i haven't had either of them on my banshee in years
try disconnecting them, if it doesn't help then you can always plug them back in
