Part: Carburetor Synchronization Tool Kit for Honda CB500K, CB550 / CB750 Motorcycles
Why You Need This: Carburetor synchronization is key to getting the carbs on a Honda CB500K, CB550 or CB750 (as well as CB350F & CB400F) to run correctly; this tool kit makes the process a breeze. If you find your bike having a high idle speed, inconsistent idle, shaking while accelerating and mediocre throttle response / power output from the engine, the carbs need synchronization. Your Honda CB500K, CB550 or CB750 probably hasn't been synced since it left the factory and more often than not we find that they were not done correctly by the dealer that sold the bike back in the day. If you have had the carbs off your bike for a rebuild than a synchronization is a MUST (if you are thinking that you didn't touch that part of the carb so it does not need adjustment, you are mistaken).
Installation Tip: Read the How-To article and watch the video. Bike must be warmed up to riding temperature, about 10 minutes of riding. Use a box fan to keep the engine cool during the process. Synchronization should only be performed after the cam chain and valves have been adjusted, ignition timing set and carburetors are clean with air filters in place. The carbs must have no air leaks from the diaphragms, intake manifolds or throttle shaft ends or the synchronization will not be accurate due to false readings.
