Servicing Your Honda

General Competition Maintenance

Perform maintenance on firm, level ground using
an optional workstand, or equivalent support.

When tightening bolts, nuts or screws, start with
the larger diameter or inner fasteners, and tighten
them to the specified torque using a crisscross
pattern.

Use Honda Genuine Parts or their equivalents
when servicing your CRF.

Clean parts in non-flammable (high flash point)
cleaning solvent (such as kerosene) when
disassembling. Lubricate any sliding surfaces,
O-rings, and seals before reassembling. Grease
parts by coating or filling where specified.

After any engine disassembly, always install new
gaskets, O-rings, cotter pins, piston pin clips, snap
rings, etc. when reassembling. After reassembly,
check all parts for proper installation and
operation.
