Keeping your CRF well maintained is absolutely
essential to your safety. It's also a good way
to protect your investment, get maximum
performance, avoid breakdowns, and have more
fun.
To help keep your CRF in good shape, this
section includes a Maintenance Schedule for
required servicing and step-by-step instructions
for specific maintenance tasks. You'll also find
important safety precautions, information on oils,
and tips for keeping your Honda looking good.

ignition timing adjustment is unnecessary. If you
want to check the ignition timing, refer to the
Honda Service Manual (page 174).

noise emission requirements of the U.S.

Maintenance, replacement or repair of the
emission control devices and systems may
be performed by any motorcycle repair
establishment or individual using parts that
are ''certified" to EPA standards.
