CHAIN LUBRICATION
The chain consists
of
many
small parts
which
operate one over another.
If
it
is
not properly
maintained,
it
will
wear
quickly.
It
is
thus necessary
to
carry out regular
maintenance work on
the chain,
especially
if
the motorcycle
is
often driven over
dusty surfaces.
The
motorcycle
is fitted
with a chain
with small O-rings
between
the plates.
Cleaning
with steam, pressurised products
and some
sol-
vents
may damage
these
rings.
Clean the chain
with
kerosene
only. After
cleaning, dry the chain
with
compressed
air
f
then lubricate well with
SAE
30W/50 engine
oil
or a special lubricant for
chains
with O-rings.
He^er use
other lubricants since they
may
contain solvents harmful
to
the O-rings.
Recommended
lubricant:
SAE
30W/50 engine
oil
