The clearance will change as the engine
temperature rises.
The adjustment must be made when the
piston is at the top of the compression stroke
when both the intake and exhaust valves
are closed.
Check the clearance of both valves by
inserting a feeler gauge (5) between the
adjusting screw (6) and the valve stem.
Clearance should be:
Intake: 0.10 mm (0.004 in)
Exhaust: 0.10 mm (0.004 in)
Finally, recheck the clearance to make sure
that adjusting has not been disturbed.

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

and realign the “T”
mark to the index mark.
