Quick Reference
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:
• Engine oil: insufficient quantity, improper oil.
• Air cleaner: dirty, leaking because of improper
installation (poor seal)
