As a rider, it is not a satisfactory issue for you at all. A worn-out or flat battery may cause this problem. In this case, the question often arises- will a bad battery cause a misfire on a motorcycle?
A bad battery can cause continuous misfiring when the motorcycle has low revs. Most motorcycles are also very prone to misfire when the rider leaves them idling for too long. It also got misfired due to the opening of certain injectors, lean fuel pumps, etc.

5 Symptoms To Recognize Your Battery Is Running Out Completely:
You can notice some specific symptoms which will let you recognize that your battery has run out thoroughly.
1. Defectiveness:
Before checking out the battery with any multimeter, take a look if it’s ok or not. Most often a bad or damaged battery will seem to be defective and deformed. You may notice that the battery becomes damaged, and gets worse due to discoloration. It’s a primary concern that your battery is going to run out completely.
2. Discharge Of Lead Acid:
One of the common symptoms of a malfunctioning battery is its built-up sulfation. Motorcycle batteries are usually made with lithium ions which may get worse and continuously discharge the lead acid. For this reason, this acid will stick to the lead plates of the battery. This particularly affects your bike battery.

3. Motorcycle Didn’t Start Properly:
Internally, you may face trouble starting the motorcycle properly. It is a familiar issue that may not be fixed until you exchange the old one for a new one.

- Bad Ignition Coil:
A bad ignition coil is not only a problem for your motorbike, but also makes a facile way of misfiring. Bad ignition means your motorbike coil won’t spark hard enough to hit the plug. Besides, a bad ignition coil didn’t provide enough protection to trigger that misfire.
