Introduction
Introduction
Congratulations on choosing your Honda CRF
motocross motorcycle.
When you own a Honda, you’re part of a
worldwide family of satisfied customers – people
who appreciate Honda’s reputation for building
quality into every product.
Your CRF is a high performance racing
motorcycle that utilizes the latest motocross
technology and is intended for competition use in
sanctioned, closed-course events by experienced
riders only.
Be aware that motocross is a physically demanding
sport that requires more than just a fine
motorcycle. To do well, you must be in excellent
physical condition and be a skillful rider. For the
best results, work diligently on your physical
conditioning and practice frequently.
Before riding, take time to get acquainted with
your CRF and how it works. To protect your
investment, we urge you to take responsibility for
keeping your CRF well maintained. Scheduled
service is a must, of course. But it’s just as
important to observe the break-in guidelines, and
perform all the pre-ride and other periodic checks
detailed in this manual.
As you read this manual, you will find information
that is preceded by a symbol. This
information is intended to help you avoid damage
to your CRF, other property, or the environment.
Unless you are mechanically qualified and have
the proper tools, you should see your dealer for the
service and adjustment procedures discussed in
this manual.
An official Honda Service Manual for your CRF is
available (page 162). It is the same manual your
dealer uses. If you plan to do any service on your
CRF beyond the standard maintenance procedures
in this manual, you will find an official Honda
Service Manual a valuable reference.
If you have any questions, or if you ever need a
special service or repairs, remember that your
Honda dealer knows your CRF best and is
dedicated to your complete satisfaction.
Please report any change of address or ownership
to your dealer so we will be able to contact you
concerning important product information.

Important Safety Precautions
Your CRF can provide many years of pleasure, if
you take responsibility for your own safety and
understand the challenges you can meet in
competitive racing.
As an experienced rider, you know there is much
you can do to protect yourself when you ride.
The following are a few precautions we consider to
be most important.
Never Carry a Passenger.
Your CRF is designed for one operator only.
Carrying a passenger can cause an accident in
which you and others can be hurt.
Wear Protective Gear.
Whether you’re practicing to improve your skills,
or riding in competition, always wear an approved
helmet, eye protection, and proper protective gear.
Take Time to Get to Know Your CRF.
Because every motorcycle is unique, take time to
become thoroughly familiar with how this one
operates and responds to your commands before
placing your machine, and yourself, in
competition.
Don’t Drink and Ride.
Alcohol and riding don’t mix. Even one drink can
reduce your ability to respond to changing
conditions, and your reaction time gets worse with
every additional drink. So don’t drink and ride, and
don’t let your friends drink and ride either.
Keep your Honda in Safe Condition.
Maintaining your CRF properly is critical to your
safety. A loose bolt, for example, can cause a
breakdown in which you can be seriously injured.
Learn and Respect Your Limits.
Never ride beyond your personal abilities or faster
than conditions warrant. Remember that alcohol,
drugs, illness and fatigue can reduce your ability to
perform well and ride safety.
2 Motorcycle Safety
Accessories & Modifications
Accessories & Modifications
Installing non-Honda accessories, removing
original equipment, or modifying your CRF in any
way that would change its design or operation,
could seriously impair your CRF’s handling,
stability, and braking, making it unsafe to ride.
WARNING
Improper accessories or modifications
can cause a crash in which you can be
seriously hurt or killed.
Follow all instructions in this owner’s
manual regarding modifications and
accessories.

Indicator
The MIL (1) on your CRF keeps you informed,
alerts you to possible problems, and makes your
riding safer and more enjoyable. Refer to the MIL
frequently.
(1)
(1) MIL
The MIL flashes when there is any abnormality in
the PGM-FI system. It should also light for a few
seconds and then go off when the engine is started.
If the MIL comes on at any other time, reduce
speed and refer to an official Honda Service
Manual available for purchase from your dealer
(page 162).
MIL Blink Pattern Current DTC/Freeze DTC
The MIL will blink the appropriate DTC number if
the ECM detects an active problem while the
engine is running at less than 4,000 rpm.
The MIL will stay on when engine speed is over
4,000 rpm.
The MIL has two types of blinks: a long blink and
short blink. The long blinking lasts for 1.2 seconds,
the short blinking lasts for 0.4 seconds.
One long blink is the equivalent of ten short blinks.
For example, when one long blink is followed by
two short blinks, the MIL is 12 (one long blink =
10 blinks, plus two short blinks).
When the ECM stores more than one DTC, the
MIL will indicate them by blinking in the order
from the lowest number to highest number.
The DTC is indicated in two ways according to the
failure status.
– In the case that the ECM detects an active
problem, the MIL will come on and will start to
blink the DTC when the engine is started.
– In the case that the ECM does not detect an
active problem but has recorded a previous
problem in its memory, the MIL will not come
on. If it is necessary to retrieve any past
problems stored in the memory, refer to an
official Honda Service Manual.
If the MIL does not come on when it should, have
your dealer check it for problems.
Instruments & Controls 7
Indicator
Circuit Inspection
Always clean around the ECM and keep debris
away from the connectors before disconnecting
them.
A faulty PGM-FI system is often related to poorly
connected or corroded connections. Check the
following connections.
(1) MAP sensor connector
(2) ECT sensor connector
(3) TP sensor connector
(4) IAT sensor connector
(5) Injector connector
(6) No.1/No.2 CKP sensor connector
(7) ECM connector
Remember, circuit inspection is not a “cure-all” for
other problems in your engine’s PGM-FI system.
