INSPECTION
The valve clearance specification is same for both valves. Valve
clearance adjustment must be checked and adjusted, 1) at the
time of periodic inspection, 2) when the valve mechanism is ser-
viced, and 3) when the camshaft is disturbed by removing it for
servicing.
NOTE:
* The piston must be at (TDC) on the compression stroke in
order to check the valve clearance or to adjust valve clear-
ance.
* The clearance specification is for COLD state.
* To turn the crankshaft for clearance checking, rotate in the nor-
mal running direction. The spark plug should be removed.
• Turn crankshaft to bring the “TDC” mark
A
on the cooling fan
to the index mark
B
on the crankcase.
• Insert a thickness gauge between the valve stem end and the
adjusting screw on the rocker arm.
If the clearance is out of specification, bring it into the speci-
fied range.
