Adjusting the clutch cable
When the engine is cold, the play at the clutch lever should be 1-3 mm
(0.04-0.12 in) (measured at the outer edge).
To adjust the clutch cable turn the adjusting nut
1 accordingly.
Checking the adjustment of the hand decompression cable*
To check, set piston at compression, so that the valves are closed. While
doing this, slowly operate the kick starter until the clicking sound (disenga-
ging) of the automatic decompression release can be heard. Now it must
be possible to operate the decompression lever 25 mm (1 in) until resi-
stance is felt (the exhaust valves begin to open). To adjust move back the
protective cover
2, loosen the counter nut 3 and correct the adjusting
screw
4 accordingly. Tighten counter nut and push back protective cover.
!
CAUTION
!
I
F THERE IS NO PLAY IN THE DECOMPRESSION LEVER, THIS CAN RESULT IN ENGINE
DAMAGE
.
NOTE:
No adjustment need be made to the automatic decompressor.
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 line branches off to a jet 4 which
sprays engine oil onto the piston pin bearing and piston head. The second
oil line 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 filters out even the finest impurities. The cleaned
engine oil is pumped through the oil line and the clutch cover into the
crankshaft to the conrod bearing
7 and drips into the crankcase. An addi-
tional 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 hole
bl the oil reaches the camshaft bm and the
valves.
