Draining of float chamber of the carburetor
Following every wet cleaning procedure, the float chamber of the carbure-
tor should be drained in order to remove any water that may have penetra-
ted into it. Water in the float chamber causes malfunction.
Perform this task on a cold engine. Close the fuel tap and place a cloth
underneath the carburetor, which is able to absorb any escaping fuel.
Unscrew the plug
1
and clean it with compressed air. Check the O-ring
and reinstall the plug. Open the fuel tap and check the float chamber for
leaks.

Oil circuit
Via the long oil screen 2 , the oil pump 1 draws engine oil from the oil
sump of the transmission. This engine oil flows through an oil line 3 into
the cylinder head for camshaft lubrication 4 ; the oil quantity is controlled
by the jet screw 5 . An oil duct branches off to the long oil filter 6 where
the coarser particles contained in the engine oil are filtered away. Then, the
engine oil arrives at the short oil filter
7 which also filters the fine particles.
Now, the purified engine oil is pumped past the bypass valve 8 to the con-
rod bearing 9 and sprayed from below onto the piston through a nozzle bk .
The second oil pump bl draws the engine oil via the short oil screen bm out
of the crankcase, thereby lubricating the transmission gears bn .
Checking the engine oil level
The engine oil level can be checked with the engine being either warm or
cold. Place the motorcycle in an upright position and on a horizontal surface
(not on the side stand).
If the engine is cold, the engine oil must be visible at the lower edge of the
inspection glass
A
.
If the engine is warm, the engine oil must be visible up to the upper edge of
the inspection glass
B
.
Replenish the engine oil, if necessary.
!
CAUTION
!
I
NSUFFICIENT AMOUNTS OF OR LOW
-
GRADE ENGINE OIL LEAD TO PREMATURE WEAR IN
THE ENGINE
.
If the inspection glass is heavily soiled (e.g. after a race in muddy terrain),
the engine oil level can also be measured with the oil dipstick. For this pur-
pose, unscrew the dipstick and wipe it clean with a cloth. Screw the dipstick
back in and screw it out again. If the engine is warm, the oil level should be
near the MAX mark
C
(+0mm –5mm) (+0in –0,2in).
