17) Holding the cutout in the crankshaft pulley aligned with the
“
” mark on the chain case, check that the “ ” mark on
the intake camshaft sprocket is in alignment with the
“ ” mark on the exhaust camshaft sprocket. (The No.1
piston is at the top dead center of its compression stroke
this time.)
• Perform this check on each cylinder with its piston at the
top dead center of its compression stroke (i.e. both the
intake and exhaust rocker arms are not lifted).
18) With the engine in the position described in step 17, check
the intake and exhaust valve clearances on the No.1
cylinder by inserting a feeler gauge between the
intake/exhaust side rocker arm valve adjusting screw and
the valve stem end.
19) If adjustment is necessary, loosen the valve adjusting lock
nut while holding the valve adjusting screw with a
screwdriver.
20) Insert a feeler gauge between the intake/exhaust side
rocker arm valve adjusting screw and the valve stem end.
21) Adjust the intake and exhaust valve clearances by turning
the valve adjusting screw.
22) After adjustment, secure the valve adjusting screw and
loosely tighten the lock nut.
23) Recheck the valve clearances again. Tighten the valve
adjusting lock nut to the specified torque.
