Revised 2021 version of one of the best available cylinders including cylinder head for Piaggio mopeds / mopeds with 10 mm piston pin.
This cast iron cylinder offers a very good power increase over the entire speed range and makes it one of the most popular 73.5 cc racing cylinder for Piaggio engines.
The workmanship is very clean and the matching of the piston windows to the overflow channels and boost parts is very good. The webs in the area of the cylinder head significantly reduce the risk of piston jamming and make the cylinder extremely durable. The cylinder head with its small combustion chamber and large flat sealing surface ensures good compression. Thanks to the additional cooling fins on the sides, this racing cylinder head can dissipate the resulting heat even better and thus protects the racing set from overheating.
Note: Before initial installation, the deco pin must be hammered into the valve seat. To do this, place the cylinder head on a stable surface with the valve ribs facing downwards and insert the pin. The deco pin must then be brought into the correct fit using a medium-strength punch and a slotted screwdriver or punch (Ø 4-6 mm). This method is unusual, but recommended by Malossi. The remaining parts required to complete the valve must be taken from the original valve.
This cylinder kit requires long-threaded spark plugs.
Attention: In order to install this cylinder on a Piaggio case, the case must be milled or honed.
Alternatively, a racing case with a larger diameter can be used for the cylinder mount.
You can find other add-on parts such as long-threaded spark plugs in the accessories section.
