Apply a thin smear of clean engine oil to the
sealing ring of the new oil filter. Install the oil
filter and tighten to 7 lbf ft (10 Nm).
Refit the catalytic converter mounting bracket
and tighten its fixings to 9 lbf ft (12 Nm).
Fill the engine to the maximum mark with a
10W/40 or 10W/50 semi or fully synthetic
motorcycle engine oil that meets specification
API SH (or higher) and JASO MA, such as
Castrol Power 1 Racing 4T 10W-40 (fully
synthetic) engine oil, sold as Castrol Power RS
Racing 4T 10W-40 (fully synthetic) in some
countries.
Start the engine and allow it to idle for a
minimum of 30 seconds.

Raising the engine speed above idle,
before the oil reaches all parts of the
engine can cause engine damage or
seizure. Only raise engine speed after
running the engine for 30 seconds to allow
the oil to circulate fully.

If the engine oil pressure is too low, the low
oil pressure warning light will illuminate. If
this light stays on when the engine is
running, stop the engine immediately and
investigate the cause. Running the engine
with low oil pressure will cause engine
damage.
Ensure that the low oil pressure warning light
extinguishes shortly after starting.
Turn off the ignition, check the oil level using
the method previously described, and top off
to between the minimum and maximum
level lines on the dipstick.
