Recommended fuel:
REGULAR UNLEADED
GASOLINE ONLY
Fuel tank capacity:
Total amount:
6.5 L
Your Yamaha engine has been
designed to use regular unleaded
gasoline with a research octane
number of 91 or higher. If knocking (or
pinging) occurs, use a gasoline of a
different brand or premium unleaded
fuel. Use of unleaded fuel will extend
spark plug life and reduce maintenance
costs.
EWA00008
Since gasoline is flammable, the
following precautions must be
observed.•
Stop the engine before
refueling.
•
Never attempt to refuel the
scooter while smoking or near
an open flame.
•
Take special care not to spill
gasoline over the engine or
muffler when refueling
immediately after operation.

PRE-OPERATION CHECKS
4The condition of a vehicle is the owner’s responsibility. Vital components can start to deteriorate quickly and unexpectedly,
even if the vehicle remains unused (for example, as a result of exposure to the elements). Any damage, fluid leakage or
loss of tire air pressure could have serious consequences. Therefore, it is very important, in addition to a thorough visual
inspection, to check the following points before each ride.
ITEM CHECKS PAGE
•Check fuel level in fuel tank.
Fuel•Refuel if necessary.3-6•Check fuel line for leakage.
•Check oil level in oil tank.
Two-stroke engine oil•If necessary, add recommended oil to specified level. 3-7•Check vehicle for oil leakage.
Final transmission oil•Check oil level and vehicle for oil leakage. 6-6
•Check operation.
•If soft or spongy, have Yamaha dealer bleed hydraulic system.
Front brake•Check fluid level in reservoir. 3-4, 6-11
•If necessary, add recommended brake fluid to specified level.
•Check hydraulic system for leakage.
•Check operation.
Rear brake•Check lever free play. 3-5, 6-11•Adjust if necessary.
•Make sure that operation is smooth.
Throttle grip•Check cable free play.
6-8
•If necessary, have Yamaha dealer adjust cable free playand lubricate cable and grip housing.
