Technical Information 141
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, carburetor adjustments,
gearing, and tire 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 color pens or pencils to
record important information on specific
subjects. For example, record results in black,
jetting changes in red, suspension/chassis settings
in blue, and gearing selections in green. Color
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:
• basic track conditions, altitude, and
temperature
• carburetion changes
• suspension settings
• chassis adjustments tested and selected
• gearing
• tire selection
• air pressure
Competition Records
• your placings
• thoughts to improve performance next time:
both yours and your CRF
• 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 or every-so-many hours of
running.
Because all races 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 six minutes represents
one tenth of an hour).
Racing Records
Information worth recording for this section of
your logbook may include:
• Your placing in each moto 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, transmission, and suspension oil
changes
• Chain, sprocket, chain guide 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.
