etcswjoe Posted September 17, 2023 Share #2 Posted September 17, 2023 Remove the Seat Remove the gas tank Remove the spark plug wires. Blow out the space around the plugs to avoid any debris getting into plug holes. Use a 18mm deep well spark plug socket and extension, remove the old plugs. Inspect the old plugs for any signs of improper wear. Gap and Install new plugs, tighten plugs to 13 ft-lb. Push plug wires on firmly. You should feel a snap when they are on all the way. GAP: 0.8-0.9 mm (0.031-0.035 in) Re-install the upper engine supports (46.1 ft-lb), gas tank (11.5 ft-lb rear bolt, 62 in.-lb front bolts) and driver's seat (62 in.-lb).
