Valve Clearance Adjustment |
|
|
|
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.
|
|
|
2.
|
Select the correct feeler gauge for the valve clearance you are going
to check.
|
|
|
Valve Clearance
|
|
Intake:
|
0.18－0.22 mm (0.008－0.008 in)
|
|
Exhaust:
|
0.23－0.27 mm (0.010－0.010 in)
|
|
|
|
no!
|
|
|
3.
|
Insert the feeler gauge (A) between the adjusting screw (B) and
the end of the valve stem on the No. 1 cylinder, and slide it back
and forth; you should feel a slight amount of drag.
|
|
|
|
|
4.
|
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.
|
|
5.
|
Tighten the locknut to the specified torque, and recheck the
clearance. Repeat the adjustment if necessary.
|
|
|
Specified Torque
|

|
7.
|
Check and, if necessary, adjust the valve clearance on the No.
3 cylinder.
|
|
|
|
|
8.
|
Rotate the crankshaft clockwise. Align the No. 4 piston TDC groove
(A) on the camshaft sprocket with the top edge of the head.
|
|
9.
|
Check and, if necessary, adjust the valve clearance on the No.
4 cylinder.
|
|
|
|
|
10.
|
Rotate the crankshaft clockwise. Align the No. 2 piston TDC groove
(A) on the camshaft sprocket with the top edge of the head.

Apply liquid gasket (P/N 08718-0004 or 08718-0009) to the chain
case contact areas. Install the component within 5 minutes of applying
the liquid gasket.
|
|
NOTE:
|
|
|
Apply a 5 mm (0.20 in) diameter bead of liquid
gasket to the mating surfaces (C).
