Starting A Cold Engine; Starting A Warm Engine - Yamaha TTR 125 2020 Owner's Manual

Starting a cold engine

The starting circuit cut-off system will
enable starting when:
 the transmission is in the neutral
position or
 The transmission is in gear with
the clutch lever pulled.
To start the engine
1. Turn the fuel cock lever to on.
2. Turn the main switch on.
3. Shift the transmission into the
neutral position.
4. Turn the starter (choke) on and
completely close the throttle. (See
page 4-6.)
5. Start the engine by pushing the
start switch or by pushing the
kickstarter lever down.
6. Release the start switch when the
engine starts, or after 5 seconds.
Wait 10 seconds before pressing
the switch again to allow battery
voltage to restore.
7. After starting the engine, move the
starter (choke) back halfway.
8. As the engine warms up, reduce
the choke.
Operation and important riding points
9. When the engine can idle normal-

ly, turn off the choke.
10. Confirm the engine is warm by
testing throttle response. When
the engine responds quickly, the
engine is warm and the vehicle
can be driven normally.
TIP
 To prevent excessive exhaust
emissions, do not use the choke
longer than necessary.
 The time necessary for choke use
depends on the ambient tempera-
ture and when the engine was last
started. The colder the tempera-
ture or the longer in-between us-
es, the longer the choke will need
to be used.
NOTICE
For maximum engine life, never ac-
celerate hard when the engine is
cold!

Starting a warm engine

Follow the same procedure as for
starting a cold engine with the excep-
tion that the starter (choke) is not re-
quired when the engine is warm.
