Engine casing -POLINI- Speed Engine, points/breaker ignition - Piaggio Ciao, Boss, Boxer, SI, Grillo, Bravo, Superbravo

The classic tuning engine cases for Piaggio mopeds.
Ideal for all Polini tuning cylinders.
By slight adjustment work, however, all other 46mm cylinders can be
driven
with the
engine housing
.

When using a racing shaft (Amt156/Amt004 or 3333812/3333813) the
timing should be checked for the used setups, because the
Polini Speedengine has a much longer intake window

.


Depending on the pole wheel used (fan wheel) it can happen that the
pole wheel grinds
in the area of the
overflow on the ignition side
.
But this can be easily and uncomplicatedly fixed with a file or a cutter.
