Tom and I sync the carbs on his 1975 Honda CB360T in the streets of Brooklyn using the Carburetor Synchronization Tool Kit:

Symptoms that your bike needs to have the carbs synced include: High idle speed, inconsistent idle, shaking while accelerating and mediocre throttle response, lack of top end power output from the engine. Chances are your CL / CJ / CB360 has not had the carburetors synchronized since it left the factory so it is time you do it.
