Starting & Stopping the Engine
Always follow the proper starting procedure
described below.
Your CRF can be kickstarted with the transmission
in gear by pulling in the clutch lever before
operating the kickstarter.

Preparation

Make sure that the transmission is in neutral.

Starting Procedure

Always follow the proper starting procedure
described as follows.
(1)
(1) fuel valve (2) choke knob
Check the engine oil, transmission oil and coolant
levels before starting the engine (pages 37, 40, 41).
Snapping the throttle or fast idling for more than 5
minutes at normal air temperature may cause
exhaust pipe discoloration.
Cold Engine Starting
1. Turn the fuel valve (1) ON.
2. Shift the transmission into neutral.
3. If the temperature is 95°F (35°C) or below,
pull the choke knob (2) fully out.
4. If the temperature is below 32°F (0°C), open
the throttle two or three times. (The engine
requires a richer mixture for starting in cold
weather. When the throttle is so opened, the
accelerator pump will feed extra fuel to the
(2)
cylinder, thereby facilitating starting in cold
weather.)
5. With the throttle closed, operate the kickstarter
starting from the top of the kickstarter stroke,
and kick through to the bottom of the stroke
with a rapid, continuous motion.
(Do not open the throttle, As the carburetor is
equipped with an accelerator pump, excessive
fuel will be charged into the engine, and the
spark plug will be fouled if the throttle is
opened and closed repeatedly. Excessive fuel
in the engine makes kickstarting difficult.)
6. About a minute after the engine starts, push the
choke knob all the way to fully OFF.
If idling is unstable, open the throttle slightly.
Starting & Stopping the Engine
Warm Engine Starting
1. Turn the fuel valve ON.
2. Shift the transmission into neutral.
3. Pull the hot start lever (1) and kick-start the
engine. (Do not open the throttle.)
4. As soon as the engine starts, release the hot
start lever.
(1)
(1) hot start lever
Starting the engine after a stall during riding or
after a fall
1. Shift the transmission into neutral.
2. Pull the hot start lever and kick-start the engine
(Do not open the throttle).
3. As soon as the engine starts, release the hot
start lever.

Flooded Engine

If the engine fails to start after repeated attempts, it
may be flooded with excess fuel. To clear a

flooded engine:

1. Shift the transmission into neutral.
2. With the throttle fully opened, repeat
kickstarter operation approximately ten times
very slowly to discharge excessive fuel from
the engine.
3. Pull the hot start lever and kick-start the
engine. (Do not open the throttle.)
4. As soon as the engine starts, release the hot
start lever.
