This video shows the two-step process on how to perform the proper carburetor synchronization on the Honda CB350 / CL350 / SL350K0 family of motorcycles. Step one - setting the idle speed synchronization, aka "bench sync." Step two - adjusting the progressive synchronization, which means having the carburetors open and close at the same rate when the throttle is twisted.
New throttle cables and a throttle sleeve ensure smooth and proper synchronization.
