11) Remove the cylinder head cover. Refer to “Engine
Top Side Disassembly in Section 1D (Page 1D-27)”.
NOTE
The valve clearance specification of intake
and exhaust valve is different.
Valve clearance (When cold)
IN.: 0.08 – 0.18 mm (0.003 – 0.007 in)
EX.: 0.18 – 0.28 mm (0.007 – 0.011 in)
12) Remove the valve timing inspection cap (10) and
starter clutch cover cap (11).
NOTE
• The cam must be at positions, “A” or “B”,
when checking or adjusting the valve
clearance. Clearance readings should not
be taken with the cam in any other position
than these two positions.
• The valve clearance should be taken when
each cylinder is at Top Dead Center (TDC)
of compression stroke.
• The clearance specification is for COLD
state.
• To turn the crankshaft for valve clearance
checking, be sure to use a wrench, and
rotate in the normal running direction.
13) Turn the crankshaft clockwise to bring the line “C” on
the starter clutch to the slit “D” of valve timing
inspection hole and also to bring the notches “E” on
the left end of both camshafts (EX and IN) to the
positions as shown in the figure.
14) Measure the clearance of valves “F”. If the clearance
is out of specification, adjust it to the specified range.
