Why would a cylinder not fire?
Damaged, worn, or bad spark plugs, or a weak ignition coil can cause a loss of spark, and therefore, a misfiring cylinder. If there is not enough gasoline in the air/fuel mixture, this can cause a misfire as well. Sometimes cylinders have intermittent misfires, which means the cylinder does not misfire all the time.
Do Harley cylinders fire at the same time?
A Harley engine has two pistons. The difference in the Harley engine is that the crankshaft has only one pin, and both pistons connect to it. This design, combined with the V arrangement of the cylinders, means that the pistons cannot fire at even intervals.
What are symptoms of a dead cylinder?
How do you diagnose a dead cylinder?
- A loss of power is the biggest indication that your vehicle needs cylinder engine repair, especially if there is also having odd vibrations.
- A loss of spark is another symptom of a misfiring cylinder in an engine.
Why do Harleys sound so bad?
Why are Harleys so loud? Many Harleys are loud because the owners want them that way. New Harleys from the factory don’t exceed the 80db limit stipulated in the U.S. EPA Code. It is Harley owners who make several aftermarket modifications on their bikes to turn up the volume.
How do you diagnose a bad cylinder?
The Most Common Symptoms of Cylinder Head Problems:
- Overheating. One of the most common symptoms of an issue with a diesel engine cylinder head is overheating.
- Poor Engine Performance. A very clear indicator of a cylinder head problem is when there is poor engine performance.
- Oil Leaks.
- Drop In Coolant Level.
- Smoke.
Is there any way to test an ignition coil?
The only safe way to test for spark is to use a spark plug tester tool. If a coil problem is suspected, measure the coil’s primary and secondary resistance with an ohmmeter. If either is out of specifications, the coil needs to be replaced. A coil can be easily bench tested with a digital 10 megaohm impedance ohmmeter.
Will removing baffles hurt my Harley?
A baffle is a specific part inside the exhaust pipe that slows down exhaust gas flow before leaving the exhaust pipe. This lessens the motorcycle engine’s noise level and also creates “back pressure” inside the system. Removing baffles on your motorcycle will not directly harm or damage the engine.
