## What is kyajet Pro?

kyajet Pro helps you approach 2-stroke Keihin® PWK carburetor tuning in a structured and understandable way.

Instead of judging every change by feel alone, you can compare setups, analyze jets and needles, and include environmental conditions in your tuning process. kyajet Pro lets you compare reference and test setups and see how changes affect different throttle ranges.

Key features:
- Compare reference and test setups
- Compare pilot and main jets
- Analyze needle codes and needle geometry
- Evaluate changes across low, mid and high throttle ranges
- Visualize setup differences
- Use the assistant to determine the next test direction
- Include air density and environmental conditions
- Save, manage, import and share setups

kyajet Pro is not designed to tell you that there is only one correct setup. It helps you evaluate changes more systematically, understand relationships more clearly and prepare your next test with better information.

Built for riders, mechanics and tuners who prefer structured comparisons over “that should probably work.”

Note:
kyajet Pro does not replace proper engine inspection or professional tuning. Carburetor and engine adjustments should always take engine temperature, plug reading, fuel, operating conditions and manufacturer specifications into account.

## Version history (last 2 releases)

### 1.4 — 2026-10-27

Kyajet Pro has come quite a way since version 1.0 - and no, we didn’t just make the version number bigger!

• Dark Mode has arrived - follow your system setting or choose Light or Dark manually.
• A more polished interface - cleaner sections, refined controls and a more consistent experience across iPhone and iPad.
• Improved wording and translations - copy has been refined and harmonized across all supported languages.
• Clearer setup analysis - labels and explanations have been improved to make results easier to understand at a glance.
• Refined environment controls - including a clearer reset function for environmental values.
• Rate Kyajet - a new menu option takes you directly to the App Store rating page. If Kyajet Pro helps your setup, a few stars are always appreciated — carburetor jets are notoriously bad at writing reviews.
• Activate your website session via QR code - the connection between Kyajet Pro and the browser version has been rebuilt and moved to the new Kyajet app platform.
• A new home for the browser app - the web app, QR activation and privacy information are now cleanly grouped under `app.kyajet.de`.
• More stability under the hood - native iOS configuration, dependencies and internal components have been cleaned up and modernized.
• Calculations still work offline - the core carburetor calculations remain available locally without requiring a permanent internet connection.

In short: fewer leftovers, more polish, and a much cleaner foundation for what comes next.
