Competition Logbook
Technical Information 183
Competition Logbook
Any serious competition effort relies heavily on
the knowledge gained and compiled from previous
racing events. The best way to organize the many
bits of information is to record them in a logbook.
Your logbook can include such information as
suspension adjustments, gearing, and tyre
selection. This detailed information, along with
your comments, can prove valuable when you
compete at the same track or on similar terrain.
Your logbook can also tell you when maintenance
was performed and when it will be necessary
again. Your logbook also lets you record any
repairs and lets you keep track of the running time
on the engine and suspension components.
If you choose to sell your CRF, the accurate
maintenance records in your logbook might be the
deciding deal-maker for a potential buyer.
Consider using different colour pens or pencils to
record important information on specific subjects.
For example, record results in black, suspension/
chassis settings in blue, and gearing selections in
green. Colour codes will help you identify the
information you want with a glance.
Tuning & Adjustment Records
Keep track of the settings and adjustments that
worked best at a particular location. These items
include:
• PGM-FI mode
• HRC-launch control system
• basic track conditions, altitude, and
temperature
• suspension settings
• chassis adjustments tested and selected
•gearing
• tyre selection
• air pressure
Competition Records
• your placings
• thoughts to improve performance next time:
both yours and your CRF’s
• strategy notes
Maintenance Records
• regular interval maintenance
• repairs
• running time on engine
• running time on suspension components
Timekeeping
This Manual lists maintenance intervals for every-
so-many races (CRF450RX)/heats (CRF450R) or
every-so-many hours of running.
Because all races (CRF450RX)/heats (CRF450R)
are not the same, the most effective way to
schedule maintenance is by the hours you have run
your CRF.
An official “guesstimate” is close enough for our
timekeeping purposes. You may choose to record
your time the same way aircraft operators do (but
without the benefit of an electrical hourmeter).
All running time is broken down into hours and
tenths of an hour (each 6 minutes represents one
tenth of an hour).
Racing Records
Information worth recording for this section of
your logbook may include:
• Your placing in each race (CRF450RX)/heat
(CRF450R) and overall finishing position.
• Thoughts on what you could do to improve
your performance next time.
• Notes on any patterns noted in choice of
starting gate positions or in riding portions of
the course as the day progressed that may
prove helpful in future events.
• Any places on the course where you chose the
wrong line and were passed too easily.
• Notes on strategy used by your competition or
by riders in another event that are worth
remembering.
Maintenance Records
Regular maintenance items you’ll want to record
in your logbook should include:
• Dates and results of cylinder, piston and ring
examinations
• Patterns for frequency of need for
decarbonization with a particular oil
• When you last performed shock linkage and
swingarm pivot bearing maintenance
• Engine and suspension oil changes
• Chain, sprocket, chain roller and slider
replacements
• Coolant changes and related component
replacements
• Spark plug, brake pad and control cable
replacements
In addition, you should record any irregularities
noted in component wear so you’ll remember to
keep a close eye on these areas in the future.
