IGNITION PROBLEMS
No spark from spark plug. Due to
the presence of high voltage, this
check should only be carried out by
an expert.
Check that the electrodes are
properly adjusted (0.7÷ 0.8 mm).
Check that the electrodes are
clean (use pure petrol and a metal
brush or an emery cloth). Check
the spark plug insulator: Replace
the spark plug if the insulator is
cracked or broken. If the spark plug
is in good conditions, contact an
Authorised Service Centre.
LACK OF COMPRESSION
Spark plug loose. Loose cylinder
head, worn piston retaining rings.
Incorrect valve clearance
Contact an Authorised Piaggio
Service Centre
HIGH CONSUMPTION AND LOW PERFORMANCE
Air filter blocked or dirty. Clean with water and shampoo and
impregnate with petrol and specific
oil («Air filter removal» section)
