% Valve clearance (when cold):
IN.: 0.10 – 0.15 mm
EX.: 0.18 – 0.23 mm
NOTE:
* The cam must be at positions,
A or B , in order to check the
valve clearance or to adjust valve clearance. Clearance read-
ings should not be taken with the cam in any other position than
these two positions.
* The clearance specification is for COLD state.
* To turn the crankshaft for clearance checking, be sure to use a
19-mm wrench and rotate in the normal running direction. All
spark plugs should be removed.
• Turn crankshaft to bring the “T” mark on the rotor to the center
of pick up coil and also to bring the notches 1 in the right ends
of both camshafts (Ex and In) to the positions shown. In this
condition, read the valve clearance at the valves C (In and Ex
of No.1 cylinder, Ex of No.2 and In of No.3).
• Use thickness gauge between adjusting screw and valve stem
end. If clearance is off the specification, bring it into the speci-
fied range by using the special tool.
