After washing or driving in wet environments (watercourses, etc.) the
carburetor float bowl should be emptied to remove any water that may
have entered. Water in the float bowl causes working problems. Carry
this operation out when the engine is cold. Close the fuel tap and place
a container underneath the carburetor to collect the fuel coming out.
Now open the screw (1) to empty the fuel and water. Re-close the
screw, open the fuel tap and control tightness of the system.
- THE FUEL IS HIGHLY INFLAMMABLE AND TOXIC. HANDLE THE FUEL
WITH CARE. NEVER CARRY OUT OPERATIONS ON THE FUEL SYSTEM
NEAR TO FLAMES OR CIGARETTES.
- ALWAYS ALLOW THE ENGINE TO COOL. USE A CLOTH TO REMOVE ANY
OVERFLOWING FUEL. MATERIALS IMPREGNATED WITH FUEL ARE ALSO
HIGHLY INFLAMMABLE. IF YOU SWALLOW FUEL OR IT COMES INTO
CONTACT WITH THE EYES, CONSULT A DOCTOR IMMEDIATELY.
- DISPOSE OF FUEL ACCORDING TO THE REGULATIONS ENVISIONED IN
YOUR COUNTRY.
OIL CIRCUIT OIL CIRCUIT OIL CIRCUIT OIL CIRCUIT OIL CIRCUIT
The delivery pump (3) sucks the oil through the net filter (4) from the
sump. The oil is delivered pressurised through a pipe (5) to the filter
cartridge where it is purified from all particles and delivered partly to
the crankshaft and partly to the distribution and gearbox.
The oil delivered to the crankshaft enters through a co-axial pipe into
the shaft and finally lubricating the big end bearing (6).
The oil delivered to the distribution and gears is made to ascend to the
top of the crankcases and, before entering the cylinder, it divides again.
A part is channeled towards the gearbox, of which it lubricates, through
a distributor (7), the gear toothing.
Another part passes through a spray nozzle towards the small end (8)
for lubrication of the piston pin.
Finally, another part is channeld along the cylinder and through a
relevant hole and arrives at the camshafts bearings and to the contact
area between the cam lobes and valve lifters (9-10).
All pressurised oil delivered to the main parts of the engine is returned
by fall and depression to the point in which the drainage pump is found
(11) which collects the oil and send it back to the oil sump.
Note that the oil sump is separate from the rotating parts of the engine
(dry sump) but integrated in the casting of the crankcases.
The oil circulation is made only by channels machined inside the engine,
without using external hoses.
