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.

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
(petrol) into the fuel tank and oil into
the oil tank.
CAUTION:
Do not allow the oil tank to empty
completely. The oil injection pump
must be bled to ensure proper oil
flow after
Otherwise, engine damage may
occur. Refer to page 4-12, "Bleeding
the Oil Injection Pump," for correct
procedure.
