Operation Component Locations
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.
Fast Idle Knob
The fast idle knob has two functions:
- When pulled out, the fast idle knob assists in first-time start-up for cold weather starting.
- When pushed in, it acts like an idle adjustment screw. Refer to Idle Speed Adjustment on page 60.
Preparation
Make sure that the transmission is in neutral.
Starting Procedure
Always follow the proper starting procedure described as follows.
Check the engine oil, transmission oil and coolant levels before starting the engine (pages 49, 52, 53).
Cold Engine Starting
- Shift the transmission into neutral.
- If the temperature is 95°F (35°C) or below, pull the fast idle knob (1) fully out.
[IMAGE] - With the throttle closed, operate the kickstarter starting from the top of the kickstarter stroke, kick through to the bottom with a rapid, continuous motion.
- About a minute after the engine starts, push the fast idle knob back all the way to fully OFF. If idling is unstable, open the throttle slightly.
Warm Engine Starting
- Shift the transmission into neutral.
- Kick-start the engine. (Do not open the throttle.)
If Difficult to Start After Stalling
- Shift the transmission into neutral.
- With the throttle fully opened, repeat kickstarter operation approximately 10 times to discharge excessive fuel from the engine.
- Kick-start the engine. (Do not open the throttle.)
Snapping the throttle or fast idling for more than about 5 minutes may cause exhaust pipe and muffler discolorations.
How to Stop the Engine
Normal Engine Stop
- Shift the transmission into neutral.
- Lightly open the throttle (1) two or three times, and then close it.
- Push and hold the engine stop button (2) until the engine stops completely.
Emergency Engine Stop
To stop the engine in an emergency, push and hold the engine stop button.
Is Your Motorcycle Ready to Ride?
Competitive riding can be tough on a motorcycle, so it’s important to inspect your CRF and correct any problems you find before each ride. Check the following items (page numbers are at the right):
WARNING: Improperly maintaining this motorcycle or failing to correct a problem before riding can cause a crash in which you can be seriously hurt or killed.
Always perform a pre-ride inspection before every ride and correct any problems.
Troubleshooting
The items that are serviceable using this Manual are followed by the page number reference in parenthesis. The items that require use of an official Honda Service Manual are followed by an asterisk (*).
