DELL'ORTO jacker caliber

Summary: The Truth Tool for Your Carburation

In competitive karting, the figure engraved on a nozzle is sometimes only an indication. Between wear, aggressive cleaning or manufacturing tolerances, a "165" nozzle can actually measure "168". The Sprinkler caliber Allows accurate measurement the inside diameter of the bore.

This tool is in the form of a graduated conical pigement or a set of precision gauges. It allows you to classify your sprinklers by actual size and to ensure that your carbu settings are reproducible from one engine to another.

- Why use a sprinkler caliber?

1. Reliability of the settings: Eliminates doubts of sprinklers whose marking is erased or incorrect.

2. Surgical accuracy: Allows you to detect a difference of some microns, crucial for high-speed performance.

3. Engine diagnosis: Help understand why a "ratatouille" engine despite a theoretically correct nozzle.

4. Longevity: Robust hardened steel tool designed to last a career of mechanic.

? Michel's trick

"The nozzle is like tires: you have to measure to know! My Pro Council: Never trust blind to laser marking. The trick: Always measure your new sprinklers as soon as the bag is exit and mark them with a small point to trace if necessary. Warning: When you insert the caliber, do it with infinite sweetness. If you force as a deaf, you will scratch the interior of the nozzle or distort the measurement. A striped nozzle creates turbulence and your carburation will never be stable! "

- User's Guide

• Measure: Insert the rope without forcing until the natural stop. Read the value on the graduation.

• Cleaning: Before calibrating, make sure the nozzle is perfectly clean (transition to ultrasound or brake cleaner + compressed air). A fuel gum deposit will distort the measurement of several points.

• Storage: Always store your caliber in its protective case to avoid marking the measuring rod.

❓ FAQ SEO (Frequently Asked Questions)

Q: Does this caliber work for Mikuni or Keihin sprinklers?

A: Yes, the diameter is universal (expressed in hundredths of a millimeter), but the tool is optimized for the bore depths of the standards DELL'ORTO (VHSH / PHBG type).

Q: Why my nine nozzle does not match the size of the caliber?

A: Dell'ORTO works with factory tolerances. A gap of 1 or 2 points is common, hence the crucial importance of this tool for high-level pilots.
