Lubrication - Yamaha F100D Owner's Manual

Maintenance
7. Just prior to turning off the engine, quickly
spray "Fogging Oil" alternately into the in-
take silencer or the fogging hole of the si-
lencer cover, if equipped. When properly
done, the engine will smoke excessively
and almost stall.
8. Drain the remained gasoline in the vapor
separator with a container. Loosen the
drain screw, and then remove the cap.
Push in the air valve with a screwdriver to
introduce air into the float chamber, so
that the gasoline will drain smoothly.
Then, tighten the drain screw.

the motor. Clean the body thoroughly.

move the spark plug(s). Pour a teaspoon-
ful of clean engine oil into each cylinder.
