Valve Clearance
Adiustment
Adjust the valves only when the cylinder head tempera-
ture is less than 100"F (38"C).
1. Remove the cylinder head cover.
Remove the middle cover (see page 6-11).
Set the No. 1 piston at TDC. The "UP" mark on the
pulleys should be at the top, and the TDC marks on
the pulleys should align with the pointers on the back
POINTERPOINTER
Adjust the valves on No. 1 cylinder.
Intake: 0.08 - 0.12 mm (0.003 - 0.005 inl
Exhaust: 0.16 - 0.20 mm (0.006 - 0.008 in)
Loosen the locknut, and turn the adiustment screw
until the feeler gauge slides back and forth with a
