Problems with the stopping
system
Faulty or no clutch lining
Engine block problems
Defective breather valve
operation
Poor piston ring seal
Excessive gap between the
guide and the inlet valve stem
Ring assembly error
Alternator problems
Insufficient or excessive
recharging
The thickness of the clutch lining normally
guarantees good braking action for the entire
duration of the engine.
If it comes away from the lever, act immediately
to stop the metal from rubbing against the fly-
wheel causing hazardous sparks.
The breather valve allows oil vapours to reach
the carburettor and so to be burned with the
air/petrol mixture; if the valve remains open, oil
could also pass through it, causing white smoke
from the exhaust.
The piston rings can wear out due to the pas-
sage of dust caused by an excessively dirty or
unoiled air filter or overheating due to the lack of
oil; in any case, the oil can pass into the com-
bustion chamber.
The excessive gap causes oil to blow back into
the combustion chamber during the inlet phase.
If the piston rings have been assembled with
their openings aligned with each other (and fac-
ing downwards), oil could pass into the combus-
tion chamber.
The alternator should deliver a current of
between 0,45 and 0,55 Amps inclusive at 2800
rpm. An insufficient charge does not retain the
optimal battery charge, which discharges more
rapidly, while an excessive charge causes obvi-
ous swelling of the casing.
