The following is a brief, but important collection
of information you need to know about your
CRF. You’ll also find space to record important
notes.
How To Avoid Costly Repairs
The engine of your CRF can be the most
expensive component to repair. Proper
maintenance, especially the use of the
recommended fluids and filters, prevents
premature wear and damage.
Frequent causes of costly engine repairs are:
• Transmission oil & engine oil: insufficient
quantity, improper oil.
• Air cleaner: dirty, leaking because of
improper installation (poor seal)

The maintenance schedule (page 25) lists service frequencies for:
each race or about 2.5 hours,
every 3 races or about 7.5 hours, every 6 races or about 15.0 hours,
every 9 races or about 22.5 hours and every 12 races or about 30.0 hours
Check the items listed on the Pre-ride Inspection checklist each time before you ride
