Tecmate Carburetor Tool

Tecmate Carburetor Tools: Precision Synchronization for Powersports Engines

When it comes to dialing in multi-carburetor or throttle-body-equipped engines, few names carry as much credibility as Tecmate. Best known globally for their OptiMate battery charging systems, Tecmate has also built a devoted following among powersports enthusiasts and professional technicians for their lineup of carburetor tools — instruments engineered to take the guesswork out of carb synchronization.

The CarbMate: Electronic Precision Over Mercury Sticks

The cornerstone of Tecmate's carburetor tool lineup is the CarbMate. The CarbMate is a cost-effective electronic replacement for mercury sticks, with the advantage of solid-state electronic measurement that won't break if you drop it. It displays the difference in vacuum intake settings of two separate carburetors — or fuel injection throttle valves — on the same engine very precisely on a single transverse "East-West" 9-LED display.

Where traditional mercury-column tools rely on visual estimation across multiple tubes, the CarbMate consolidates everything into one intuitive readout. A single green LED at the dead-center "happy face" mark indicates that the compared manifold vacuums are equal to within the selected resolution — making it immediately clear when your carburetors are in perfect balance. Adjustable resolution accuracy of 2–0.5 cmHg meets the 0.5 cmHg standard recommended by motorcycle and outboard marine OEMs.

An industrial- and medical-grade Motorola pressure transducer sits at the heart of the CarbMate's measurement system, giving it the kind of sensor-level reliability typically reserved for professional shop equipment. The instrument is powered from an external 12V source or the vehicle's own 12V battery.

The ROTAX Kit: Aviation-Grade Carb Sync

Tecmate takes the CarbMate a step further with the CarbMate ROTAX Kit, purpose-built for aircraft applications. It can synchronize carburetors on V-twin, opposed "boxer" twin, or parallel twin motorcycle or aircraft engines. It is approved as a recommended tool by Rotax aviation's official club, ROTAX OWNER. The kit includes an ABS instrument case with durable polycarbonate labels, fuel- and oil-resistant rubber hoses, a protective rubber holster, a DC supply socket with a power lead ending in battery clips, a nylon carry case, and ROTAX adapters.

VacuumMate: Multi-Cylinder Synchronization

For engines with more cylinders to balance, Tecmate offers the VacuumMate series. The VacuumMate Allweather is designed for precise and rapid synchronization of up to four carburetors or fuel injection throttle valves, and includes fuel- and oil-resistant rubber hoses, a DC power lead with battery clips, 4x M5 and 4x M6 flexi-rigid adapters, and a fuel switch T-piece. It can even be expanded to six cylinders with an optional adapter, making it one of the most versatile carb sync tools available for powersports applications.

Adapters and Accessories for Hard-to-Reach Ports

Tecmate's carburetor tool ecosystem goes beyond the synchronizers themselves. Their range of manifold adapters addresses one of the most common frustrations in carb sync work: inaccessible vacuum ports. The extended vacuum adapter includes santoprene hose and is ideal for permanent mounting on sport bikes or any vehicle where access to the carburetor or fuel-injection synchronizing ports requires removal of side panels, air filters, or the fuel tank. The unique flexi-rigid adapter easily allows synchronization of machines with difficult-to-reach 5 mm or 6 mm carburetor or fuel-injection vacuum ports — simply bend the outer sheath to the appropriate angle and turn the inner tube to thread the brass fitting into the vacuum port.

Why Choose Tecmate for Carburetor Synchronization?

Tecmate develops and manufactures professional and consumer diagnostic tools, including engine troubleshooting and tuning tools, aimed at the power sport, automotive, marine, light aircraft, medical, e-bike, and industrial equipment industries.
