i need some help with my throttle stop screw does anyone have part number for a yz(preferably) or wr throttle stop screw for a 1998. I went to cut my wr screw down and there was no screw to be found. Im assuming the previous owner removed it instead of cutting it down. Or what diameter screw it is so i could go to a parts store. I went to the dealer and they said the only way to get a screw is to buy the carb housing as well. i just want it fixed so the throttle doesnt hang at the wrong moment.
