Main Jet #96 for Vintage Vespas and Mopeds
This #96 main jet is a key part for running a range of scooters and mopeds well. It is made to suit vintage Vespa models and similar engines. Because the jet meters how much fuel moves through the carburetor, it belongs with the scooter carburetors & jets lineup. If you are tuning the engine or making changes to it, this jet may be needed to improve how it performs.
What the Jet Sizes Mean
This jet sits in the main jet stack and has a cone shape. Its job is to control fuel flow, and the available sizes run from 82 to 165. Most vintage Vespas generally work with jets in the 85 to 116 range. That said, if the engine has been upgraded for more power, a larger jet may be required to supply the extra fuel it needs.
Things to Know Before Fitting
Swapping the main jet usually takes some trial and adjustment before the engine runs the way you want. Changing the jet size will affect how the scooter responds, so check the jetting guidance before you start for the most reliable outcome. This part goes into the same spot the original jet came out of, so the swap is simple for anyone comfortable with scooter maintenance.
