Servicing Your Honda

General Competition Maintenance

Perform maintenance on firm, level ground using 
the side stand, 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.
