With an absolute accuracy of 0.299% or better, the most accurate Vortex RoK  jetting software money can buy!

The 2009 version of JET-TECH RoK includes some major new features. Jet-Tech RoK is the only software available that supports the Dellorto Variable Jet Kit. This is the kit available for the 2009 season, announced by Vortex in December 2008 - Dellorto Part Number: R.9305

Users can select their language option by simply clicking on the national flag. Languages supported include English, German, French and Italian.

The accuracy of the Pressure, Temperature and Humidity data you enter into your application has a direct bearing on the accuracy of the end result!

JET-TECH provides you with a unique copyright feature that will calibrate your barometer to an absolute accuracy of 0.299% or better. This process provides the perfect Software / Barometer combination and ensures that JET-TECH remains the most accurate Kart Jetting Software money can buy.

With the software un-locked, the user can select between Super, Rok or Junior engines. The software will automatically compensate for the different configurations. When the button is first selected, it provides the default setting for that particular engine/carb configuration. The user can then establish their own settings and when the button is pressed again, it will save the new configuration. Different setups can be saved to each button, enabling you to easily recall them. Both NGK and Denso Plug options are also provided.

In addition to selecting the floats, float heights (in 1mm increments) can be selected and recorded - from a drop down list. This allows the user to fine tune their carburettor setup, allowing for the effect that float height has on jetting.

With the main screen un-locked, the user can switch between any of the Dellorto K Series of needles used in RoK. Similarly, any of the Dellorto needle jets for RoK (250-292) can be selected from drop down lists, at the click of a button. Your selected settings are automatically saved and the screen can be locked again to prevent accidental changes.

Jet-Tech RoK fully supports the 2009 Dellorto Variable Jet Kit announced by Vortex in December 2008. From the main configuration screen users can select this option if required.  If you are using the kit (R.9305) you can select the variable jet and main jet option (200, 220 or 250) from the list.

The adjustment is shown in hours and minutes notation. In the example screen shot, a 200 main jet has been selected and a setting in this instance, for the variable jet shows 1:45M. So you would turn the variable jet out 1 3/4 turns. Using this method, you can adjust your main jet to an accuracy of 1/60th turn of the variable jet.

Why do you need Jet-Tech RoK when using the variable jet kit? SAVE YOUR ENGINE!

The range of the Dellorto main jets when used with the variable jet is dramatic - from the equivalent of a 140 to a 190 main jet! In some instances a 1/4 turn can mean the difference between a main jet equivalent from 170 to 160. So accuracy is critical in ensuring that you not only maintain peak performance of your engine but also to eliminate the risk of seizing your engine.

Only Jet-Tech RoK with this unique and copyright feature can give you the correct settings and parameters to safely configure your carburettor.

Jet-Tech Flow-Bench © is the very latest Copyright feature of Jet-Tech RoK and is designed to enable the user to perfectly match Carburettor, Engine, Exhaust and Jet-Tech Software for all racing conditions and states of engine tune.

Because the Dellorto range of carburettors are a mass produced item, no two will Flow air and fuel exactly the same and whilst Jet-Tech RoK will, for 99.9% of carburettors, mirror the performance exactly, it may be that your engine tuner/builder has optimised your engine and/or exhaust pipe in a particular way that requires a different jetting and needle curves to get the maximum power and torque out of your carb and engine combination.

If this is the case and/or you want to experiment with your carbs set-up and performance across all air density ranges, then the latest Copyright features of Jet-Tech Flow-Bench are what you have been waiting for.

You can now set-up even more accurately how Jet-Tech RoK operates and the jetting answers it gives you for all Air Density values (Temperature, Humidity and Pressure), and adjust the rate of change of main jet and needle clip settings required, relative to changes in Air Density - bearing in mind of course, that for 99.9% of users, it will already be operating exactly how you want it to without any further adjustments being made.

Flow-Bench within Jet-Tech RoK, can also be used to fine tune the Variable Jet settings if you are using the 2009 Dellorto Variable Jet Kit.

Jet-Tech Flow-Bench together with all the other unique features of the Jet-Tech Software range give you the opportunity to increase your understanding of carburetion and the effects of different carburettor setups on your engine's performance, thus enabling you to maximise the full potential of your engine/exhaust/carb combination. 

JET-TECH RoK continually monitors the Dew Point Temperature and displays a Carb Ice warning when atmospheric conditions are such that Carburettor Ice may form.

This feature is an essential aid for Professional or Amateur carburettor tuner alike. It adds another dimension to understanding fully the performance envelope of the Dellorto carburettor.

JET-TECH RoK comes with fully searchable, context sensitive help files. The help files for each screen are easily reached by pressing F1 on your computer keyboard or clicking on the ? in the bottom left of the screen.

JET-TECH RoK is a sophisticated yet easy to use application that has been designed and tested by racing professionals. It has unrivalled accuracy and flexibility, easily adaptable to changing rules and regulations.
