If the oxygen sensor cables are not connected, the ECU will not be able to get an accurate reading of the oxygen content in the exhaust gas. This can cause the engine to run rich or lean, which can lead to reduced performance, increased emissions, and damage to the engine.
In addition, the oxygen sensor cables may also be used to heat the oxygen sensor. This is important because the oxygen sensor must be heated to a certain temperature in order to function properly. If the oxygen sensor is not heated, it will not be able to provide accurate readings to the ECU.
Therefore, it is important to make sure that the oxygen sensor cables are connected properly. If you are not comfortable doing this yourself, you should take your motorcycle to a qualified mechanic.
