3 bolts up front for the oil cooler and bracket. 5mm and 6mm allen bolts. 13mm nut on the left bolt only, craftsman open end wrench will work fine. 2 more 6mm allen bolts at the rear, one is through the pulley. Loosen the clamps next. Also loosen the right foot peg bracket, 2 bolts. Exhaust should almost fall off the bike at that point.
