Lubrication
1) Remove the spark plug(s). Spray a
Yamaha “Stor-Rite Engine Fogging Oil”
into each cylinder for 10 seconds.
Grease the spark plug threads and
reinstall the spark plug(s) and torque to
proper specification.
(Refer to the
“CLEANING AND ADJUSTING SPARK
PLUG”).
2) Turn the engine over with the stop lan-
yard disconnected to work the fogging
oil into the piston rings.
3) Change the gear-case oil. (Refer to
“CHANGING GEAR OIL”). Inspect the
oil for the presence of water which indi-
cates a leaky seal. Seal replacement
should be performed by an authorized
Yamaha dealership prior to use.
4) Grease all grease fittings. (Refer to the
“GREASING”)
