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”).

lanyard disconnected to work the fog-
ging oil into the piston rings.

oil for the presence of water which
indicates a leaky seal. Seal replace-
ment should be performed by an
