44 Servicing Your Honda
Before & After Competition Maintenance (Off-Road Use Only)
It is important to the long term performance of
your motorcycle to practice a consistent
maintenance program. Right after the event is a
good time to begin your next maintenance cycle.
After Race
Lubrication
Apply a light coating of rust-inhibiting oil to the
drive sprocket and any steel portions of the chassis
or engine where the paint has worn away.
This will prevent rusting of the exposed metal.
Apply rust-inhibiting oil more heavily if the event
was particularly wet or muddy. Take care to avoid
spraying any oil near the brake pads or the brake
discs.
Take care to prevent catching your fingers between
the chain and sprocket.
Remove the drive chain, clean and lubricate it
(pages 131, 132). Be sure the chain is wiped clean
and is dry before lubricating the chain.
Routine Cleaning
If your motorcycle is only slightly dirty, it is best
to clean it by hand with the aid of a stiff bristled
nylon brush and some clean rags.
Take care to prevent catching your fingers between
the chain and sprocket.
A variety of reasonably priced cleaning brushes
are available from variety, drug, food, and
hardware stores. Some of these brushes are
extremely useful in removing dirt from the many
tight contours of the metal pieces of your
motorcycle. Avoid using stiff, abrasive brushes on
the plastic or rubber parts.
If your motorcycle was exposed to sea air or salt
water, rinse it as soon as possible after the event,
dry it, and apply a spray lubricant to all metal parts.
If you decide to wash your motorcycle or use
cleaners, refer to Appearance Care (page 141).
