Starting & Stopping the Engine
Basic Operating Instructions 15
Starting & Stopping the Engine
Always follow the proper starting procedure
described below.
Your CRF can be started with the transmission in
gear by pulling in the clutch lever before operating
the kickstarter or start button.
Make sure that the transmission is in neutral.
Turn the fuel valve ON.
The three-way fuel valve is used to control the
flow of fuel from the fuel tank to the carburetor.
ON–Turning the fuel valve ON before attempting
to start the engine allows fuel to flow from the fuel
tank to the carburetor.
OFF–Turning the fuel valve OFF prevents the
flow of fuel from the fuel tank to the carburetor.
RES–Turning the fuel valve to RES allows fuel to
flow from the reserve fuel supply to the carburetor.
Always follow the proper starting procedure
described as follow.
Check the engine oil, transmission oil and coolant
levels before starting the engine (pages 44, 47, 48).
Snapping the throttle or fast idling for more than 5
minutes may cause exhaust pipe discoloration.
To restart a warm engine, follow the procedure for
“High Air Temperature.”
Normal Air Temperature 10°C-35°C (50°F-95°F)
1. Turn the fuel valve (1) ON.
2. Pull the choke knob (2) fully ON, if the engine
is cold.
3. Keep the throttle fully closed.
4. Pull the clutch lever all the way in, and depress
the start button. Or operate the kickstarter to
start the engine. Starting from the top of the
stroke, kick through to the bottom with a rapid,
continuous motion. Do not operate the throttle.
NOTICE
Allowing the kickstarter to snap back freely
against the pedal stop can damage the engine
case.
5. Warm up the engine; don’t operate the throttle.
6. About 15 seconds after the engine starts, push
the choke knob all the way to fully OFF. If
idling is unstable, open the throttle slightly.
NOTICE
Extended use of the choke may impair piston and
cylinder wall lubrication and damage the engine.
