12) Similar to measurement procedures used for
#1 cylinder, measure the #2, #3 and #4 cylinder
valve clearances.
NOTE:
• Be sure to set the cylinder pistons to their re-
spective top dead centers on compression stroke
before measuring valve clearances.
• To set the #3, #2 and #4 cylinder pistons to their
top dead centers on compression stroke, turn the
crankshaft pulley clockwise 90° at a time starting
with arrow mark on camshaft sprocket (LH) facing
up.

B: ADJUSTMENT
NOTE:
Adjustment of the valve clearance should be per-
formed while engine is cold.
1) Set the #1 cylinder piston to top dead center of
compression stroke by rotating crankshaft pulley
clockwise using socket wrench.
NOTE:
When arrow mark (A) on the camshaft sprocket
(LH) comes exactly to the top, #1 cylinder piston is
brought to the top dead center of compression
stroke.
2) Adjust the #1 cylinder valve clearance.
(1) Loosen the valve rocker nut and screw.
(2) Place suitable thickness gauge.
(3) While noting the valve clearance, tighten the
valve rocker adjuster screw.
(4) When specified valve clearance is obtained,
tighten the valve rocker nut.
Tightening torque:
10 N·m (1.0 kgf-m, 7.2 ft-lb)
CAUTION:
• Insert the thickness gauge in as horizontal a
direction as possible with respect to the valve
stem end face.
• Adjust the exhaust valve clearances while
lifting up the vehicle.
