Carburetor upgrade kit for Malossi's Vespa race cases. This will not fit your stock cases. This is only for the Malossi reed valve cases. If you have the reed cases, you probably weren't planning on using a 13.13 SHA. This is the perfect upgrade. The included 19mm PHBG will let your engine breathe like it should!
Comes with everything needed for installation. Snug fitting design will even sit nicely inside a Ciao frame.
