How to Cool a Harley Engine?


You’re wondering how to cool a Harley engine. There are a few basic techniques that will help you get the best performance from your motorcycle’s engine. These include installing free-flowing exhaust slip-ons, adding cooling fins, and closing the right side fairing lower vent. This article will walk you through each step of the process so you can maximize your motorcycle’s performance. Once you’ve mastered these techniques, you can start improving your motorcycle’s performance today!

Air-cooling vs liquid-cooling

If you’re looking for an adventure motorcycle with more power and torque, there are a few options to consider: air-cooled or liquid-cooled. In this article, we’ll discuss the pros and cons of both options. Besides the performance and flexibility of air-cooled Harley engines, both methods also reduce heat generated by an engine. This is good news for riders who want to enjoy their long rides, but you should understand which one is right for you.

Free flowing exhaust slip-ons

There are several benefits to adding free flowing exhaust slip-ons to your Harley motorcycle. Using these accessories can drastically reduce the temperature of your engine. Standard Harley exhaust mufflers are quite restrictive, which causes the engine to work against itself, creating a lot of heat. Free flowing exhaust slip-ons are more open and allow the exhaust to flow freely. Free flowing headers are also a good option to reduce the amount of felt heat from the exhaust.

Adding cooling fins

Adding cooling fins to a Harley-Davidson engine can drastically reduce engine temperatures. These engines are notoriously hot, and can easily overheat, even at cruising speed. Since air-cooling is the most common method of cooling motorcycle engines, adding cooling fins will give your bike a much more pleasant ride. A Harley with air-cooling is susceptible to overheating, which can damage the engine’s performance and be uncomfortable for both you and your passengers.

Closing the right side fairing lower vent

Despite the lower vents’ functionality, closing them completely won’t reduce the amount of heat the passenger feels. Keeping them closed, however, will reduce the amount of air passing through the engine. You should consider this if you plan to ride the bike in the rain. It might also increase the risk of experiencing a spike in temperature. So, if you can close them, do so.

Changing the oil

If you own a Harley, you should change the motor oil every few thousand miles. It can last up to ten thousand miles before it needs to be changed. However, if you use synthetic oil, you can go as high as ten thousand miles before you need to change the oil. Motorcycle oil has different properties that make it different from other types of oils. One thing you should know about it is the temperature of the motor oil. The higher the temperature, the quicker your motorcycle will wear out and eventually cause it to stop working.
