1. Remove the “Timing Hole Cap” (1)
2. Remove the cylinder head cover.
3. Rotate the flywheel counterclockwise
until the “T Mark” (2) on the flywheel
lines up with the “Index Mark” (3) on the
crankcase. In this position, the piston
may either be on the compression or
exhaust stroke.

This condition can be determined by
moving the rocker arms. If they are free,
it is an indication that the valves are closed
and that the piston is on the compression
stroke. If they are tight and the valves are
open, rotate the flywheel 360 degree and
realign the “T” mark to the index mark.
Check the clearance of both valves by
inserting a “Feeler Gauge” (4) between the
“Adjusting Screw” (5) and the valve stem.
Clearance should be:
Intake:0.10 mm (0.004 in)
Exhaust:0.15 mm (0.006 in)
If it is necessary to make an adjustment,
loosen the “Adjusting Screw Lock Nut” (6)
and turn the adjusting screw so there is a
slight resistance when the feeler gauge in
inserted.

After completing the adjustment, tighten the
adjusting screw lock nut while holding the
adjusting screw to prevent it from turning.
Finally, recheck the clearance to make sure
that adjusting has not been disturbed.
