Changing the engine oil (SX, SC)*
The engine oil change is to be carried out when the engine is still warm.
WARNING
A
N ENGINE HAVING BEEN RUN WARM, AND THE ENGINE OIL IN IT ARE VERY HOT - DO NOT
BURN YOURSELF
.
Place the motorbike on a horizontal surface. Remove the two plugs (
1 and 2),
and drain oil into a container.
!
CAUTION
!
T
HE SCREW PLUG A MUST NOT BE REMOVED, THIS IS PART OF THE BY-PASS VALVE.
Clean the plugs thoroughly with a fireproof solvent and compressed air, in order
to remove the metal abrasion. After all the oil has drained through, clean raised
and flat faces and install plugs with seals. Tighten plug 1 with 30 Nm (22
ft.lb)and plug
2 with 20 Nm (15ft.lb).
Remove oil dipstick on the clutch cover and fill with 1.5 litre engine oil (Shell
Advance Ultra 4).
Warm up engine, check engine oil level and refill up to the marking MAX. Finally
check the oil system for leaks.
Changing and bleeding the microfilter (SX, SC)*
Replace the microfilter while changing the engine oil. To do so, remove hexagon
screws
3 and take off the microfilter cover 4. Remove the microfilter, clean its
parts and check the O-ring on the microfilter lid for signs of damage. Before
installing the new micro filter, soak it in clean engine oil. Place a new microfilter
in the filter housing, apply a thin layer of grease to the O-ring and mount the
microfilter cover.
It is necessary to bleed the micro filter so that all friction areas can be quickly sup-
plied with engine oil. To do this, fill with oil and remove the jet screw
6 from the
oil line on the clutch cover. Start the engine and close off the oil filler hole on the
clutch cover with a rag. Allow the engine to run at idle until oil runs out of the oil
line
5. Turn the engine off. Install seal rings and the jet screw. Torque the jet
screw to 10 Nm and check for leaks.
Oil circuit (EGS)
The oil pump 1 pumps the engine oil past the by-pass valve 2 through the oil fil-
ter
3. After the oil filter, an oil lead branches off to a jet 4 which sprays engine
oil onto the piston pin bearing and piston head. The second oil lead takes the
main flow of oil into the front pipe of the frame
5, where the engine oil is cooled
down. Afterwards the engine oil runs through the fine screen filter
6, which fil-
ters out even the finest impurities. The cleaned engine oil is pumped through the
oil lead and the clutch cover into the crankshaft to the connecting rod bearing
7
and drips into the crankcase. An additional oil pump 8 sucks the engine oil out of
the crankcase and pumps it through the oil line
9 to the gear wheels of the 4th
and 5th gear. Via the gear wheels, the engine oil reaches the oil sump. The timing
chain
bk runs through the oil sump and transports the engine oil upwards to the
cylinder head. Through the bore
bl the oil reaches the camshaft bm and the
valves.
