3.4 Valve clearance
Valve clearance inspection and adjustment must
be done with the engine cold.
Remove the cylinder head cover, and set the
piston at top dead center of the compression
stroke (both valves will be fully closed).
1. Measure the clearance between the rocker
arm and the valve stem with a feeler gauge.
Intake: 0.10-0.15 mm
Exhaust: 0.15-0.20mm
To adjust valve clearance, hold the rocker arm
pivot and loosen the pivot lock nut.
2. Turn the rocker arm pivot to obtain the
specified clearance.
3. Hold the rocker arm pivot and tighten the pivot
lock nut.
4. Recheck the clearance and readjust if necessary.
5. Install the cylinder head cover.
