Changing the engine oil *
NOTE: When changing the engine oil, it is necessary to clean the short and
long oil screens and to replace the oil filter.
Engine oil has be changed with the engine at an operating temperature.
An engine at operating temperature and the engine oil it contains are very hot
– do not burn or scald yourself.
Place the motorcycle on a horizontal surface, remove the plug [1] and allow
the oil to drain into a receptacle.
Clean plug (with magnet) thoroughly.
Once the entire oil has been drained, clean the sealing surface, mount the
plug together with the sealing ring and tighten it to 20 Nm.
CLEANING THE SHORT OIL SCREEN
The short oil screen [2] is accommodated in the hex-socket plug at the engine
bottom. Insert a pin-type key into the plug and tap on the key a few times
with a hammer in order to relieve the stress acting on the plug. Dismount the
oil screen, clean the components thoroughly and blow compressed air through
them. Check the O-rings for damage and, if necessary, replace them. Mount
the oil screen together with the plug (oiled) again and tighten the plug to
10 Nm.
CLEANING THE LONG OIL SCREEN
The long oil screen is accommodated in the hexagon plug [3] adjacent to the
engine number. Dismount the plug together with the oil screen, clean the com-
ponents thoroughly and blow compressed air through them. Check the O-rings
for damage and, if necessary, replace them.
To mount the long oil screen [4], place it on an approx. 300 mm (12 in) long
pin-type key or a similar tool. Insert the pin-type key through the opening into
the bore of the opposite engine casing wall. Then, push the oil screen into
the engine casing as far as possible. Remove the pin-type key, mount the plug
and tighten it to 15 Nm.
The oil screen is mounted slightly downwards, incorrectly fitted, the screen
looses its function and this can cause increased engine wear.
