The History of Harley-Davidson Engines
Harley-Davidson, the American motorcycle manufacturer, is known for producing some of the most iconic motorcycles in history. Central to its success has been its signature engines that have powered these machines. The company’s long and illustrious history with engines began over a century ago.
The first Harley engine was built in 1903 and was a single-cylinder 26 cubic inch (425 cc) unit. By 1911, the company had developed its first V-twin engine, which became an instant hit with motorcyclists across America. This engine featured two cylinders arranged at an angle to each other with a common crankshaft and proved to be much more powerful than previous versions.
In the following years, Harley continued to refine its engine technology, experimenting with different configurations such as inline fours and opposed twins. However, it was the V-twin that remained at the heart of their designs through much of their history.
One notable development came in 1929 when Harley introduced its “45” flathead engine. This new design featured fewer moving parts than previous models while producing greater power output. It quickly became popular among riders who valued simplicity and reliability on long rides.
By the early 1930s, competition from Indian Motorcycles spurred further innovation from Harley-Davidson as they sought ways to outdo their main rival on both speed and performance fronts.
In response to this challenge came perhaps one of Harley’s greatest inventions –the Knucklehead Engine– which debuted in 1936. This new design represented a major departure from earlier models; it boasted overhead valves instead of side-valves along with aluminum heads that improved cooling capabilities substantially.
Over time additional innovations followed including Panhead Engine (1948), Shovelhead Engine (1966), Evolution Engine (1984), Twin Cam Engine (1999), and Milwaukee-Eight Engine (2017). Each of these engines built on the legacy of its predecessors, introducing new technologies and refining existing ones.
Today, Harley-Davidson remains one of the most respected names in the motorcycle industry thanks to its long history with engine innovation. Their current line-up boasts some of the most powerful and advanced engines available on any bike today.

An air intake upgrade allows more air into your bike’s combustion chamber, resulting in better throttle response and improved overall performance. A high-flow air filter combined with a cold-air intake kit is an excellent option for those who want maximum gains from their upgraded motor.
4. Fuel Management System
To ensure your new upgrades work efficiently together without causing damage or running poorly on fuel delivery aspects; it’s recommended that you install a fuel management system (FMS). FMS ensures that all parts get enough fuel under any circumstance while also regulating emissions levels according to local laws or regulations.
In Conclusion,
Upgrading to the Harley 117 engine is an excellent way to increase your bike’s performance, and there are several modifications that you can make to enhance its output even further. Whether you’re looking for more low-end torque or higher horsepower, upgrading your bike with a new camshaft, exhaust system, air intake upgrade and fuel management system will help you achieve your desired results.
Maintenance and Care for the Harley 117 Engine
Maintaining and caring for your Harley 117 engine is crucial to keeping it running smoothly and ensuring its longevity. The following are some tips on how to take care of your engine:
Oil Changes
Regular oil changes are essential in maintaining the performance of your engine. It is recommended that you change your oil every 5,000 miles or earlier depending on usage. Use only high-quality oil that meets the specifications outlined in your owner’s manual.
Fluid Levels
Check all fluid levels regularly, including coolant, brake fluid, and transmission fluid. Low levels can cause damage to the engine components and affect performance.
Air Filters
Air filters should be checked at least once a year or more frequently if you ride in dusty areas. A dirty air filter restricts airflow to the engine, causing poor performance.
Tire Pressure
Keeping proper tire pressure is not only important for safety but also affects fuel economy and handling.
Battery Maintenance
Battery maintenance includes checking connections, keeping it clean from debris, charging regularly when not in use during winter months.
Cooling System Maintenance
The cooling system should be flushed out periodically as per manufacturer’s recommendations to prevent buildup of sediments which can eventually harm the motor over time.
In summary, regular maintenance checks will help keep your Harley 117 engine running smoothly while promoting longevity. Consult with a trained mechanic if you have any doubts about performing any of these tasks yourself or if something doesn’t seem right concerning how well-engine performs overall!
