INSPECTION
The valve clearance specification is different for intake and
exhaust valves. Valve clearance adjustment must be checked
and adjusted, 1) at the time of periodic inspection, 2) when the
valve mechanism is serviced, and 3) when the camshaft is dis-
turbed by removing it for servicing.
$ Valve clearance (when cold):
Standard: IN. : 0.05 – 0.10 mm
EX. : 0.17 – 0.22 mm
Tighten initially at 1 000 km (600 miles, 3 months) and
every 4 000 km (2 500 miles, 20 months) thereafter.
Inspect initially at 1 000 km (600 miles, 3 months) and
