Lubrication
(7)
Commercially prepared drive chain lubricants
may be purchased at most motorcycle shops and
should be used in preference to motor oil. Pro
Honda Chain Lube or an equivalent, or SAE 80
or 90 gear oil is recommended.
Saturate each chain joint so that the lubricant
penetrates the space between adjacent surfaces of
the link plates and rollers.
