1. Position push rod guide plate on cylinder head with
extruded edges down over push rod bores. Secure
by installing rocker arm pivot studs. Torque studs to
13.5 N·m (120 in. lb.).
2. Note mark or tag identifying push rod as either
intake or exhaust. Apply grease to ends of push
rods. Insert push rods into push rod bores and seat
lower end into dimpled recess of cam levers. It may
be necessary to lift or shift lower end of push rod
slightly, and feel rod seats into recess.
3. Apply grease to contact surfaces of rocker arms and
adjusting nuts and install them onto pivot studs.
4. With engine at TDC of compression stroke, insert a
0.127 mm (0.005 in.) fl at feeler gauge between end
of 1 valve and rocker arm. Turn adjustment nut with
a wrench until a slight drag is felt on feeler gauge.
Hold nut in position and torque set screw (T15 Torx
drive) to 5.5 N·m (50 in. lb.). To prevent damage to
nut, torque Torx screw only. Perform adjustment
procedure on other valve. After tightening, recheck
adjustment. Proper valve clearance is 0.101/0.152
mm (0.004/0.006 in.).

burrs.
2. Apply a 1.5 mm (1/16 in.) bead of sealant to valve
cover as shown. Position valve cover and start
mounting screws.

into new holes, or 6.8 N·m (60 in. lb.) into used
holes, using sequence shown.
Install Spark Plug
1. Check gap using wire feeler gauge. Adjust gap to
0.76 mm (0.030 in.).
2. Install plug into cylinder head.
