Cylinder Head Valve Clearance Adjustment
NOTE: Adjust the valves only when the cylinder head temperature is less than 38 °C (100 °F).
  1. Set the No. 1 piston at top dead center (TDC). The ‘‘UP'' mark (A) on the camshaft sprocket should be at the top, and the TDC grooves (B) on the camshaft sprocket should line up with the top edge of the head.
  1. Select the correct thickness feeler gauge for the valves you are going to check.
    Valve Clearance
    Intake:
    0.15−0.19 mm (0.006−0.007 in.)
    Exhaust:
    0.26−0.30 mm (0.010−0.012 in.)

  1. If you feel too much or too little drag, loosen the locknut, and turn the adjusting screw (A) until the drag on the feeler gauge is correct.
  1. Tighten the locknut and recheck the clearance. Repeat the adjustment, if necessary.
  1. Tighten the locknut to the specified torque, and recheck the valve clearance. Repeat the adjustment if necessary.
    Specified Torque
    7 x 0.75 mm 14 N·m (1.4 kgf·m, 10 lbf·ft)
    Apply new engine oil to the nut threads.

  1. Rotate the crankshaft clockwise. Align the No. 3 piston TDC groove (A) on the camshaft sprocket with the top edge of the head.
  1. Check, and if necessary, adjust the valve clearance on the No. 3 cylinder.
  1. Rotate the crankshaft clockwise. Align the No. 4 piston TDC groove (A) on the camshaft sprocket with the top edge of the head.
  1. Check, and if necessary, adjust the valve clearance on the No. 4 cylinder.
  1. Rotate the crankshaft clockwise. Align the No. 2 piston TDC groove (A) on the camshaft sprocket with the top edge of the head.
  1. Check, and if necessary, adjust the valve clearance on the No. 2 cylinder.
