Checking the engine oil level
The engine oil level can be checked when the engine is cold or warm.
To check, place the motorcycle in an upright position on a level surface.
If the engine is cold, the oil level should be visible at the lower edge
A of
the inspection glass.
If the engine is warm, the oil level should be visible at the upper edge
B of
the inspection glass.

Oil circuit
The oil pump 1 pumps the engine oil past the by-pass valve 2 through the
oil filter
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 to the microfilter
5, which filters 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
6 and drips into the
crankcase. An additional oil pump
7 sucks the engine oil out of the crank-
case and pumps it through the oil line
8 to the gear wheels of the 4th and
5th gear.
Via the gear wheels, the engine oil reaches the oil sump. The timing chain
9 runs through the oil sump and transports the engine oil upwards to the
cylinder head. Through the bore
bk the oil reaches the camshaft bl and the
valves.
