8. Fit the liner into the crankcase ensuring that the
arrow
on
the piston faces to the right hand side of
the engine/bike (the same side as the exhaust
headers).

• Ensure that the piston/liner/connecting rod
assemblies align correctly
with
the
crankpins
during
assembly into the
crankcase.

End
Always renew the big end bolts. The bolts are
torqued near to their yield point when first installed
and are severely weakened if reused. Re-using the
original bolts may cause bolt breakage resulting
in
engine damage, loss of motorcycle control and
an
accident.

9.
Align the connecting
rod
to the crankshaft and fit
the
big
end cap. Tighten the NEW cap bolts as
follows:
The torque characteristics of the connecting rod
bolts are sensitive to the rate at which they are
tightened. If all the torque is applied
in
one action,
the bolts will
be
stretched beyond their yield point.
This may cause bolt breakage resulting
in
engine
damage, loss of motorcycle control and
an
accident.
Lubricate the under-head
and
thread areas of the
bolts with undiluted molybdenum disulphide grease.
Tighten the bolts,
in
two stages as follows;-
a)
Tighten to
14
Nm.
b)
Tighten through 120
