Description

This Tutti Ricambi #100 main jet gives you a specific fuel-metering option for dialing in your Dellorto or Spaco SI carburetor. Whether you are bringing a vintage Vespa back to life or fine-tuning a compatible Stella 150 2T, selecting the right main jet helps your engine receive the fuel it needs when you open the throttle.

Features

SI carburetor fit: Installs at the bottom of the main jet stack in compatible Dellorto and Spaco SI carburetors
#100 sizing: An individual tuning option for matching fuel delivery to your engine setup; larger main-jet numbers allow more fuel flow
Brass construction: Compact cone-shaped jet with a slotted end for servicing
Sold individually: Buy the jet size you need without purchasing a complete assortment

Choose the size for your engine: Physical compatibility does not make #100 the correct stock or tuning size for every vehicle above. Jet selection depends on your engine, intake, exhaust and operating conditions. This is an SI main jet, not an idle jet or air-corrector jet, and is not intended for SHA, SHB, PHBG, CVK or Keihin jet systems.
