The SynchroKing 4S is a universal synchronization/balancing tool for both carburettors and throttle valve bodies. The SynchroKing 4S is primarily designed for use with 2,3 or 4 cylinder motorcycles of any make (Honda, Kawasaki, Suzuki, Yamaha, BMW, Triumph, Harley Davidson), but is in principle suitable for any 2,3 or 4 cylinder combustion engine as long as it is fitted with vacuum ports on the inlet manifolds. The SynchoKing 4S comes with M5 and M6 fittings that allow it to connect to virtually any motorcycle model and make.
The SynchroKing 4S is designed to make it as easy as possible for the user to measure and adjust the throttle valve to achieve smooth running and optimal performance of the vehicle. Properly balanced throttle valves will improve throttle response, power output and fuel economy.
The main numerical indicators provide a readout of the vacuum in the inlet manifold in mmHg [mm of mercury, 600mm range and 2mm resolution. This enables the user to adjust the vacuum in the manifold to the desired/EOM specified level.
The bar displays show an instant comparison between the vacuums in the inlet manifolds. This provides direct indication of the appropriate adjustment of the throttle valve. Each bar segment represents 2mmHg difference in vacuum compared to the other manifold; The benefit of this is that the user does not need to eyeball and compare two bouncing gauges or mercury columns as is the case in conventional balancing tool; Each bar segment simply shows in which direction to adjust and by how much.
The SynchroKing 4S runs from the vehicles electrical power but will accept and 6-15V DC supply, so does not require batteries. It comes with a built-in power lead and clamps for connection to the vehicle battery poles.
The amount of signal dampening is adjustable by means of the adjustment knob. This function is used to smoothen-out a fluctuating vacuum in the manifolds to produce a usable readout. Conventional balancing devices require hosed to be cut to have restrictor plugs or choke valves installed which is fiddly and an unreliable method to dampen the signal the readout.
