Cooling water

Check for a steady flow of water from the
cooling water pilot hole. A continuous flow of
water from the pilot hole shows that the wa-
ter pump is pumping water through the cool-
ing passages. If the cooling passages are
frozen, it may take a while for water to start
flowing out of the pilot hole.

NOTICE
If water is not flowing out of the pilot hole
at all times while the engine is running,
overheating and serious damage could
occur. Stop the engine and check wheth-
er the cooling water inlet on the lower
case or the cooling water pilot hole is
blocked. Consult your Yamaha dealer if
the problem cannot be located and cor-
rected.
Check that no water leaks from the joints be-
tween the exhaust cover, cylinder head, and
body cylinder.

Choke start models

shorten engine life. Gradually return the
choke knob to its home position as the en-
gine warms up.
