Latest Rage Deluxe Carburetor Airflow Meter Pro-Sync — Universal 1–30 kg/h Scale, Non-Restrictive Visual Synchronizer

The Latest Rage Deluxe Carburetor Airflow Meter (Pro-Sync) is a visual, precision tool that balances multiple carburetors quickly and accurately without restricting airflow.

The Pro-Sync Deluxe by Latest Rage is a universal carburetor synchronizer engineered for side-draft and down-draft setups. Built to help enthusiasts and mechanics tune dual and multiple-carb systems on vehicles such as dune buggies, VW Beetles, Karmann Ghias, VW buses and motorcycle trikes, this instrument delivers a clear visual reference to match airflow across each carburetor throat. It uses a numbered 1–30 kg/h scale and a low-restriction design so you can synchronize with confidence and minimal engine disturbance.

How does the Pro-Sync show which carburetors are out of balance?

The meter uses a visible float/indicator that moves against a numbered scale, letting you compare airflow between carburetors side by side. When the indicators read different values, you know which carb needs adjustment. This straightforward display removes guesswork and speeds up the tuning process.

• Clear 1–30 kg/h numbered scale for direct comparison
• Float indicator gives instant visual feedback
• Works on both side-draft and down-draft carburetors
• Non-restrictive airflow design preserves running conditions

What vehicles and carb setups is this tool compatible with?

The Pro-Sync is built as a universal synchronizer, suitable for classic VW air-cooled engines, custom dune buggies, motorcycles with twin carbs, and many other multi-carb applications. It adapts to most intake configurations where visual airflow balancing is required. The tool’s flexibility makes it useful for restoration projects and routine maintenance alike.

• Dual and multiple carb systems (twin, triple configurations)
• Side-draft and down-draft carburetors
• Classic VWs, dune buggies, trikes, and motorcycle applications
• Aftermarket and OEM carb setups that accept vacuum/sync tools

How precise is the synchronization and what makes it easy to use?

Precision comes from the Pro-Sync’s clearly numbered scale and responsive indicator, enabling fine adjustments until readings match. The meter is calibrated to display airflow in easy-to-read kg/h increments, which helps you achieve consistent balance across all throttles. Its non-restrictive pathway keeps engine idling and throttle response stable during measurement.

• 1–30 kg/h scale for fine-tuning accuracy
• Responsive float gives repeatable readings
• Non-blocking design prevents throttle disturbance
• User-friendly visual interface suitable for beginners and pros

What accessories or setup steps are required to use it effectively?

Using the Pro-Sync generally requires basic vacuum hoses and adapters to connect each carburetor to the meter; most garages already have the needed fittings. Mount the meter where the gauges are visible, start the engine to a stable idle, then adjust each carb linkage until indicators match. The product is compact and designed for straightforward bench or engine-bay use.

• Vacuum hoses and common adapters for carb fittings
• Stable idle and a safe working environment for adjustments
• Standard hand tools for throttle linkage tuning
• Optional second person to operate throttle while you read indicators

Who is this for? The Latest Rage Deluxe Carburetor Airflow Meter is ideal for classic-car restorers, hobbyist mechanics, motorcycle tuners, and professional shops that need a simple, reliable way to synchronize multiple carburetors. If you tune dual or multiple carb setups and want a visual, accurate method that doesn’t impede airflow, the Pro-Sync offers a practical, durable solution for routine maintenance and performance tuning.
