Dellorto SHA 12.xx 13.xx

The Dellorto SHA 12.xx 13.xx carburetor family is like the SHA 14.xx 15.xx family, but more compact. They have a smaller air filter flange, 50mm instead of 58. This style of carburetor was original on all Vespa/Piaggio mopeds 1970’s, 1980’s, 1990’s, and 2000’s. In the USA it was on 1972-86 Vespa mopeds, 1983-86 Garelli VIP-N, and mid 1990’s Kinetic TFR mopeds. 

Improved choke: These carburetors have an improved choke release trigger, that cures the sticking trigger lever problem that the 14.xx 15.xx SHA has. Vespa types have a sliding push rod, that moves up a ramp in the throttle slide when the throttle is raised fully. The solid rod pushes the choke lever/plate over a little stop tab. The torsion spring is then free to snap it back off. The top is relatively easy to put on, with only the throttle slide and spring to install, no choke device that gets damaged easy.

 


Vespa (Piaggio) Carburetors


On 1972-79 Vespa mopeds (US models) there were 3 carb bodies, 7, 10, and 12mm, 5 jet sizes, 39, 41, 43, 45, 49, and 2 air filter boxes, 3-hole and 6-hole. The Boxer had a side-pull carb top assy, like Peugeot. It gives more frame clearance. After 1979 the Boxer became the Si. There were 4 choke levers, Grande, Bravo, Ciao, Boxer. The later Boxer 2 had the linkage type choke with pull wire.

 

1980s Vespa Carburetors
On 1980-83+ Vespa mopeds (US models) there are 3 carb bodies, 7, 10, and 12mm, 4 jets, 39, 42, 45, 49. The Ciao P and Bravo P had top pull, and Si had a side-pull carb top assy. There are 3 choke levers, Bravo-Ciao, and Si, linkage type, and Grande. There are 2 air filter boxes, 3-hole and 6-hole. Some are newer designs.
