• Rotate the generator rotor to set the No.1 cylinder’s piston at
TDC of the compression stroke. (Rotate the rotor until the “
R”
line on the rotor is aligned with the center of hole on the gen-
erator cover.)
• To inspect the No.1 cylinder’s valve clearance, insert the thick-
ness gauge to the clearance between the valve stem end and
the adjusting screw on the rocker arms.
# Valve clearance (when cold):
IN. : 0.10 – 0.15 mm
EX.: 0.18 – 0.23 mm
% 09900-20806: Thickness gauge
• If the clearance is out of the specification, bring it into the speci-
fied range by using the special tool.

Both right and left valve clearances should be as closely
set as possible.
• Rotate the generator rotor 450 degrees (1-¼ turns) and align
the “
F” line on the rotor with the center of hole on the genera-
tor cover.
• Inspect the No.2 cylinder’s valve clearance as the same man-
ner above.
