of increased deposits in the combus-
tion chamber. When enough deposits
collect, piston rings begin sticking.
Performance drops and engine wear
increases dramatically.

While many additives available may
reduce deposits, Yamaha recommends
the use of Ring Free Fuel Additive,
available from your Yamaha dealer.
Ring Free has repeatedly proven its
ability to clean combustion deposits
from inside the engine, notably in the
critical piston-ring-land area, and fuel
system components. Follow product
labeling for use instructions.

ENGINE OIL

Recommended oil: YAMALUBE 2-W. If
YAMALUBE 2-W is not available,
another 2-cycle engine oil with a
NMMA

®

-certified TC-W3

™

rating may

be used.

OIL INJECTION

SYSTEM

These engines use Yamaha's oil injec-
tion system, which provides superior
lubrication by ensuring the proper oil
ratio for all operating conditions. No
fuel premixing is necessary (except
during break-in). Simply pour gasoline
into the fuel tank and oil into the oil
tank.

Do not allow the oil tank to empty
completely. The oil injection pump
must be bled to ensure proper oil
flow after the tank empties.
Otherwise, engine damage may
occur. Refer to page 4-13. “Bleeding
the Oil Injection Pump," for correct
procedure.
