Malossi reed valve cases for Vespa Ciao, Bravo, Si, Grande, etc! These cases are already big enough for the kits that require case boring. Bolts right up! You'll probably want to use the Malossi full cheek race crankshaft.
This version is for CDI. This will not work with a Kinetic CDI either! Comes with a 13mm intake adapter, gaskets, seal, nuts, bolts, reed valve, and a top for Dellorto SHA carburetors.
