f. Remove and Install Control Wire Housings. Remove either control wire housing after following procedure outlined above (step b), then remove set screw on under side of handle bar, just ahead of grip sleeve shoulder. NOTE: Set screw for spark control wire housing is located under headlight dimmer switch. After set screw is removed and housing freed from attaching clamps, housing can be pushed out through end of handle bar.
