TwinMax Electronic Carburetor Balancer

An electronic differential depression gauge. A carburetor and fuel injector throttle body balancer. It is light, compact, transportable, and accurate to 1mm of mercury.

THE BENEFITS OF CORRECT CARBURETOR BALANCE
With use, the chain of cables, rods and linkages that connect the throttle to the carburetors will stretch and change their tolerances which results in the carburetor sliders or butterflies operating at slightly different times from one another. This produces an imbalance in the carburetion of the engine due to unequal amounts of air entering the cylinders at any given time. Carburetor balance, or synchronization, is essential for the efficient running and longevity of your engine. Any imbalance in the timing, or amount of, throttle opening amongst the carburetors on your engine will result in reduced performance, poor throttle response, excessive fuel consumption, increased vibration and increased stress on the crankshaft and bearings.

THE ADVANTAGES OF THE TWINMAX BALANCER
Other balancers use either dial gauges or tubes containing mercury or spring-loaded weights with one gauge per cylinder and any adjustments to the carburetors are made according to the readings on each of these gauges. This means that not only is there the potential for errors due to the moving parts of each gauge, it is very difficult to ensure that each gauge gives exactly the same reading on a given amount of vacuum, due to variances in manufacturing tolerances, friction differences, volumes of mercury or tension of springs. The TWINMAX is different. The TWINMAX works by comparing the vacuum present on either side of a single pressure sensor and shows this difference as a meter reading. The carburetor being calibrated at that time is then adjusted until there is no deviation on the meter! No potential errors and only one reading to make at any time!
Synchronizing carburetors with the TWINMAX is simple, quick and gives professional level accuracy every time! Regular balancing of your carbs with the TWINMAX will ensure your engine performs at its best at all times.

USING THE TWINMAX
Carburetor synchronization is easy to achieve, provided you can use a small wrench, a screwdriver and a pair of pliers! The theory is simple-each carburetor has either a sliding valve (known as a slider) or a twisting valve (known as a butterfly valve). When the throttle is used, a combination of cables and rods (depending on the machine) is activated, opening or closing the valves in the carburetors and regulating the volume of gas/air mixture allowed into the engine. If these valves do not begin to open at exactly the same time and by precisely the same amounts, the motor will be unbalanced or unsynchronized. This causes vibration, poor fuel consumption, poor throttle response, reduced performance and can stress crankshafts and bearings. Regular use of the TWINMAX eliminates these problems and leaves you with a beautifully running engine.

NOTE: BMW Hose adaptors are included. M5 (5mm) and M6 (6mm) vacuum hose adaptors for non-BMW motorcycles must be purchased separately and are sold individually. You will need 2.
