tors are a just a piece of shit yamaha put on for safety reasons. (if your throttle sticks it cuts out the engine). if you dont have the money you can just unplug it BUT, they make a kit to get all the bullshit wiring off of the shee's also getting rid of the tors it makes it ALOT easier to pull the carbs to make adjustments or to clean. do yourself a favor go spend the $50 unhook the tors on the carbs throw them in the garbage, unhook the black box and disconnect the throttle wires and be done with it there junk they will cause you problems. the only thing you lose by elimating the tors is the headaches it will cause eventually.
