MAINTENANCE
Rotate the crankshaft counter clockwise, and align the
“
T
” mark on the flywheel with the index notch on the left
crankcase cover.
Make sure the piston is at TDC (Top Dead Center) on the
compression stroke.
This position can be obtained by confirming that there is
slack in the rocker arm. If there is no slack, it is because
the piston is moving through the exhaust stroke to TDC.
Rotate the crankshaft one full turn counter clockwise and
match up to the “
T
” mark again.
Check the valve clearance by inserting a feeler gauge
between the adjusting screw and valve stem.
Clean the feeler
gauge with a
soft cloth before
usage. When
checking the
clearance, slide
the feeler gauge
from the center
toward the
outside.

Adjust by loosening the valve adjusting lock nut and turning
the adjusting screw until there is slight drag on the feeler
gauge.
