Adjustable Air Bleed Jet Packs

When installing a ThunderJet™ in any S&S carb, we recommend modifying the fixed-size main jet air bleed circuit to accept jets for additional tuning versatility. Instructions on how to perform this effective modification externally on the carb body for easy access are included with this kit. Air bleed jet kit includes 4 jet sizes for most popular applications.
