You have to have both cam covers off heads to see rear of cams and timing marks. Also you have to have right tire and front inner fender liner off to see crankshaft pulley.
You need a 41mm (1 5/8") socket to turn crankshaft CLOCKWISE (CW) to line up Top Dead Center (TDC) line on front crankshaft pulley with pointer on front engine cover. It helps to have sparkplugs out so engine will turn easier.
Turn engine clockwise with socket wrench to line up TDC marks on front crankshaft pulley and then check timing marks on rear of each cam. If none appear lined up turn engine again 360 degrees CW and with front pulley back on TDC marks recheck cam timing marks.
