B. STORAGE
Long term storage (60 days or more) of your
machine will require some preventive proce-
dures to guard against deterioration. After thor-
oughly cleaning the machine, prepare for stor-
age as follows:
1. Fill the fuel tank with fresh fuel and add fuel
stabilizer (if available).
NOTE:
Use of fuel stabilizer eliminates the need to
drain the fuel system. Consult a Yamaha dealer
if the fuel system is to be drained instead.
2. Remove the spark plug, pour about one
tablespoon of SAE 10W30 or 20W40 motor
oil in the spark plug hole and reinstall the
spark plug. Ground the spark plug wire and
turn the engine over several times to coat
the cylinder wall with oil.
3. Clean the drive chain thoroughly and lubri-
cate it. (See page 8-65.)
