Proper carb synchronization is the key to a sweet running bike. When carb sync is out of whack, you can have a poor idle, poor off-idle response, “hanging” throttle and lazy return to idle. You can even suffer from fouled plugs if one or more throttle butterflies are opening early, thereby partially activating the carb’s progression circuitry. Very small adjustments will have a major impact on idle smoothness!
