This compact, cone-shaped jet sits at the bottom of the main jet stack and governs how fuel is metered into the engine. Choosing the right jet can noticeably affect how a scooter runs and how efficiently it uses fuel.

Vintage Vespas generally use jets in the 85 to 116 range, whereas engines that have been modified often need larger jets to supply the extra fuel they burn.
