Packningssats -ATHENA- 63cc Ø43mm Piaggio Ciao, Bravo, Si, Boxer

Good basis for steady tuning. Original carburettor can be used, for even more power a bigger carburettor should be installed.

Delivery without cylinder head, therefore a bigger one should be used, or the standard head should be adapted.

Designed for models with the 10 piston pin diameter. On some engine cases the cylinder mount must be spindled/adjusted.
