Polini Set of 5 Universal JetRef : POL00389A / 1126147

Set of 5 POLINI Dellorto Jets 125 to 137 — a kit designed for tuners and demanding riders looking to fine-tune the carburation of their Dellorto carburetor. Each jet is machined with great precision: Polini controls the diameter of the passage hole to the thousandth to ensure a consistent and reproducible change in richness.

• Usage: primarily affects the last 3/4 of the throttle opening, with a lesser influence on medium openings.
• Content: set of 5 jets covering sizes from 125 to 137, ideal for quickly testing multiple settings.
• Audience: suitable for tuners, mechanics, and riders wishing to finely adjust carburation.
• Practical advantage: multi-size box for conducting tests and finding the jet that corrects overly rich or lean carburation over a given usage range.

This POLINI kit complements the range of individual jets and saves time during adjustments on the bench or on the road. A piece signed by POLINI, manufacturer reference: 363.0003.
