PRE-OPERATION CHECKS
4The condition of a vehicle is the owner’s responsibility. Vital components can start to deteriorate quickly and unexpect-
edly, even if the vehicle remains unused (for example, as a result of exposure to the elements). Any damage, fluid leak-
age or loss of tire air pressure could have serious consequences. Therefore, it is very important, in addition to a thor-
ough visual inspection, to check the following points before each ride.

sure to check the oil pressure as
described below.11. Remove the air bleed screw, and
then start the engine. If oil does
not seep out of the hole after a
few minutes, immediately stop
the engine and have a Yamaha
dealer check for the cause. If oil
seeps out of the hole, turn the
engine off and install the air
bleed screw.12. Start the engine, and then let it
idle for several minutes while
checking it for oil leakage. If oil is
leaking, immediately turn the
engine off and check for the
cause.

and can lead to chain slippage or
breakage. To prevent this from
occurring, keep the drive chain
slack within the specified limits.3. Tighten the axle nut and the
brake caliper bracket bolt to the
specified torques.2. Wipe the drive chain dry.
3. Thoroughly lubricate the drive
chain with a special O-ring chain
lubricant.
