CAUTION:
Excessive water pressure may cause water
seepage and deterioration of wheel bearings,
brakes, transmission seals and electrical de-
vices. Many expensive repair bills have result-
ed from improper high pressure detergent
applications such as those available in coin-
operated car washers.4. Once the majority of the dirt has been hosed
off, wash all surfaces with warm water and
mild, detergent-type soap. An old toothbrush
or bottle brush is handy for hard-to-get-at
places.
5. Rinse the machine off immediately with clean
water and dry all surfaces with a chamois,
clean towel or soft absorbent cloth.
6. Clean the seat with a vinyl upholstery cleaner
to keep the cover pliable and glossy.

B. STORAGE
Long term storage (60 days or more) of your ma-
chine will require some preventive procedures to
guard against deterioration. After thoroughly
cleaning the machine, prepare for storage as fol-
lows:
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 ta-
blespoon 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. Lubricate all control cables.
4. Block up the frame to raise all wheels off the
ground.
