rectly. It must open smoothly and spring back to
the idle position when released. Have a Yamaha
dealer repair as necessary for proper operation.

Fittings and fasteners
Always check the tightness of chassis fittings and
fasteners before a ride. Take the machine to a
Yamaha dealer or refer to the Service Manual for
correct tightening torque.
EBU01003
Lights
Check the headlights and tail/brake light to make

Starting a warm engine
To start a warm engine, refer to the “Starting a cold
engine” section. The starter (choke) should not be
used. The throttle should be opened slightly.
EBU00538
Warming up
To get maximum engine life, always warm up the
engine before starting off. Never accelerate hard
with a cold engine! To see whether or not the en-
gine is warm, check if it responds to the throttle
normally with the starter (choke) turned off.NOTE:When the parking brake is used, engine speed is
limited to 2,300 r/min. Be sure the parking brake is
released before moving the throttle lever. Other-
wise, the engine will misfire, preventing normal op-
eration.
