5 Symptoms of Harley low primary oil
You already know that Harley Davidson motorcycles are known for their powerful engines, but proper maintenance is key to keeping them running well.
One of the most important maintenance tasks is checking the overfilled primary Harley level. Low primary oil levels can cause serious damage to the engine, so it’s important to be aware of the symptoms and take action quickly if you notice them. Here are some symptoms of Harley low primary oil:
Motor Runs Hotter Than Normal
If your engine overheats so much that it runs hotter than it used to, your bike may be low on oil.
Some bikes have a temperature gauge that tells you when your bike is overheating. But most of the Harley Davidson 2021 models have a digital meter that reads your engine temperature.
An overheating engine is always a serious problem, but if your motorcycle is air-cooled, the problem must be corrected. An air-cooled motorcycle’s engine can overheat in hot weather when it idles too long in traffic; All the more reason to pull over and check your oil level on the fly.
As your bike’s engine warms up, make sure your oil is at the proper level to avoid damaging engine parts.
Smell Burning Metal While Riding
When you smell burning metal while riding, it’s usually your Harley Davidson’s oil that is burning. This is caused by the oil not being thick enough to lubricate your engine properly. As a result, the metal on metal parts starts to grind against each other, creating friction and heat.
This problem can be solved by changing your primary oil to a heavier-weight oil. Heavier oils will create more friction, but they will also provide more lubrication for your engine. You can also try adding a viscosity modifier to your current oil, which will thicken it up and help it to stay in place better.

Motorcycle’s Motor Makes Metallic Clanking Sounds
You may hear metallic clanking sounds from your bike engine. This is one of the early signs of low oil in Harley and is a sign that there is something wrong with your engine. Clanking noises can be caused by a variety of problems, including metal shavings in the engine, bearing failure, or a loose rod.
Clean oil is a lubricating layer of protection between high-revving and hard-functioning metal engine components. When your oil level is correct, and at an appropriate level, your engine sounds clean and tight.
If the bike is low on oil, your engine parts will lose that protective coating of lubrication and create a racket of metallic clanking louder than usual. When you hear strange engine noises, especially metal on metal, stop riding and take it to a mechanic immediately.
Motorcycle Fails to Run
If the level of your Harley’s primary oil is too low, you may experience difficulty when starting the bike. If the engine won’t start or idles unevenly, check the primary oil before you start ruling out other potential problems. It could be that your bike has insufficient primary oil and is having trouble firing up.
This can be a challenge if it’s your first time changing the oil yourself and you don’t know what to do to get it going again. But don’t worry, professional mechanics have years of knowledge and experience with this issue and should be able to help you get back on your bike quickly.
Check Oil Light Stays On
When the bike is low on primary oil, you will want to see if the check oil light is on while the bike is running. This is a definite warning sign that the oil level is too low and should be topped up immediately.
If you find that the check oil light is still on after refilling the oil tank, it may indicate a more serious problem such as a blocked or damaged gasket or seal. In this case, it is best to take your bike in for servicing so that an expert can properly diagnose and repair the problem before further damage occurs.
Factors That Can Cause the Primary Oil Level to Drop
Several factors can cause the primary oil level on your Harley-Davidson motorcycle to drop.
One of the most common causes is riding a motorcycle in hot weather. When the engine gets too hot, the oil can start to vaporize, causing it to drop in level. Other factors that can contribute to a low primary oil level include riding at high speeds for an extended period, carrying a heavy load on the motorcycle, and using the wrong type of oil.
If you’re experiencing any of the symptoms of a low primary oil level, it’s important to take action right away. Not only can it damage your engine, but it can also be dangerous to ride your motorcycle with insufficient oil.
